-<h1>Active Record Class</h1>
-
-<p>CodeIgniter uses a modified version of the Active Record Database Pattern.
-This pattern allows information to be retrieved, inserted, and updated in your database with minimal scripting.
-In some cases only one or two lines of code are necessary to perform a database action.
-CodeIgniter does not require that each database table be its own class file. It instead provides a more simplified interface.</p>
-
-<p>Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications, since the query syntax
-is generated by each database adapter. It also allows for safer queries, since the values are escaped automatically by the system.</p>
-
-<p class="important"><strong>Note:</strong> If you intend to write your own queries you can disable this class in your database config file, allowing the core database library and adapter to utilize fewer resources.<br /></p>

-
-<h1><a name="select">&nbsp;</a>Selecting Data</h1>
-
-<p>The following functions allow you to build SQL <strong>SELECT</strong> statements.</p>
-
-<h2>$this->db->get();</h2>
-
-<p>Runs the selection query and returns the result. Can be used by itself to retrieve all records from a table:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT * FROM mytable</code>
-
-<p>The second and third parameters enable you to set a limit and offset clause:</p>
-
-<code>$query = $this->db->get('mytable', 10, 20);<br />
-<br />
-// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)</code>
-
-<p>You'll notice that the above function is assigned to a variable named <kbd>$query</kbd>, which can be used to show the results:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>Please visit the <a href="results.html">result functions</a> page for a full discussion regarding result generation.</p>
-
-
-<h2>$this->db->get_where();</h2>
-
-<p>Identical to the above function except that it permits you to add a "where" clause in the second parameter,
-instead of using the db->where() function:</p>
-
-<code>$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);</code>
-
-<p>Please read the about the where function below for more information.</p>
-<p class="important">Note: get_where() was formerly known as getwhere(), which has been removed</p>
-
-<h2>$this->db->select();</h2>
-<p>Permits you to write the SELECT portion of your query:</p>
-<p><code>
-$this->db->select('title, content, date');<br />
-<br />
-$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code></p>
-<p class="important"><strong>Note:</strong> If you are selecting all (*) from a table you do not need to use this function. When omitted, CodeIgniter assumes you wish to SELECT *</p>
-
-<p>$this-&gt;db-&gt;select() accepts an optional second parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks. This is useful if you need a compound select statement.</p>
-<p><code>$this-&gt;db-&gt;select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE); <br />
-$query = $this-&gt;db-&gt;get('mytable');<br />
-</code></p>
-<h2>$this->db->select_max();</h2>
-<p>Writes a "SELECT MAX(field)" portion for your query. You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_max('age');<br />
-$query = $this->db->get('members');<br />
-
-// Produces: SELECT MAX(age) as age FROM members<br />
-<br />
-$this-&gt;db-&gt;select_max('age', 'member_age');<br />
-$query = $this-&gt;db-&gt;get('members');<br />
-// Produces: SELECT MAX(age) as member_age FROM members</code></p>
-
-<h2>$this->db->select_min();</h2>
-<p>Writes a "SELECT MIN(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_min('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT MIN(age) as age FROM members</code></p>
-
-<h2>$this->db->select_avg();</h2>
-<p>Writes a "SELECT AVG(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_avg('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT AVG(age) as age FROM members</code></p>
-
-<h2>$this->db->select_sum();</h2>
-<p>Writes a "SELECT SUM(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_sum('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT SUM(age) as age FROM members</code></p>
-
-<h2>$this->db->from();</h2>
-
-<p>Permits you to write the FROM portion of your query:</p>
-
-<code>
-$this->db->select('title, content, date');<br />
-$this->db->from('mytable');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code>
-
-<p class="important">Note: As shown earlier, the FROM portion of your query can be specified in the <dfn>$this->db->get()</dfn> function, so use whichever method
-you prefer.</p>
-
-<h2>$this->db->join();</h2>
-
-<p>Permits you to write the JOIN portion of your query:</p>
-
-<code>
-$this->db->select('*');<br />
-$this->db->from('blogs');<br />
-$this->db->join('comments', 'comments.id = blogs.id');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: <br />
-// SELECT * FROM blogs<br />
-// JOIN comments ON comments.id = blogs.id<br />
-</code>
-
-<p>Multiple function calls can be made if you need several joins in one query.</p>
-
-<p>If you need a specific type of JOIN you can specify it via the third parameter of the function.
-Options are: left, right, outer, inner, left outer, and right outer.</p>
-
-<code>
-$this->db->join('comments', 'comments.id = blogs.id', <strong>'left'</strong>);<br />
-<br />
-// Produces: LEFT JOIN comments ON comments.id = blogs.id</code>
-
-
-
-
-
-<h2>$this->db->where();</h2>
-<p>This function enables you to set <strong>WHERE</strong> clauses using one of four methods:</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically, producing safer queries.</p>
-
-<ol>
- <li><strong>Simple key/value method:</strong>
-
- <code>$this->db->where('name', $name);
- <br /><br />// Produces: WHERE name = 'Joe' </code>
-
- <p>Notice that the equal sign is added for you.</p>
-
- <p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
- <code>$this->db->where('name', $name);<br />
- $this->db->where('title', $title);<br />
- $this->db->where('status', $status);
- <br /><br />// WHERE name = 'Joe' AND title = 'boss' AND status = 'active' </code> </li>
-
- <li><strong>Custom key/value method:</strong>
-
- <p>You can include an operator in the first parameter in order to control the comparison:</p>
-
- <code>$this->db->where('name !=', $name);<br />
- $this->db->where('id <', $id);
- <br /><br />// Produces: WHERE name != 'Joe' AND id < 45 </code> </li>
- <li><strong>Associative array method:</strong>
-
-
- <code>
- $array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
- $this->db->where($array);
- <br /><br />// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active' </code>
-
- <p>You can include your own operators using this method as well:</p>
-
- <code>
- $array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);<br /><br />
-
- $this->db->where($array);</code> </li>
- <li><strong>Custom string:</strong>
-
- <p>You can write your own clauses manually:</p>
-
- <code>
- $where = "name='Joe' AND status='boss' OR status='active'";<br /><br />
- $this->db->where($where);</code></li>
- </ol>
-
-
-<p>$this-&gt;db-&gt;where() accepts an optional third parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks.</p>
-<p><code> $this-&gt;db-&gt;where('MATCH (field) AGAINST (&quot;value&quot;)', NULL, FALSE);<br />
-</code></p>
-<h2>$this->db->or_where();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->where('name !=', $name);<br />
-$this->db->or_where('id >', $id);
-<br />
-<br />// Produces: WHERE name != 'Joe' OR id > 50</code>
-
-<p class="important">Note: or_where() was formerly known as orwhere(), which has been removed.</p>
-
-
-<h2>$this->db->where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with AND if appropriate</p>
-<p><code>
- $names = array('Frank', 'Todd', 'James');<br />
- $this->db->where_in('username', $names);<br />
- // Produces: WHERE username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
- $names = array('Frank', 'Todd', 'James');<br />
- $this->db->or_where_in('username', $names);<br />
- // Produces: OR username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with AND if appropriate</p>
-<p><code>
- $names = array('Frank', 'Todd', 'James');<br />
- $this->db->where_not_in('username', $names);<br />
- // Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
- $names = array('Frank', 'Todd', 'James');<br />
- $this->db->or_where_not_in('username', $names);<br />
- // Produces: OR username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->like();</h2>
-<p>This function enables you to generate <strong>LIKE</strong> clauses, useful for doing searches.</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically.</p>
-
-
-<ol>
- <li><strong>Simple key/value method:</strong>
-
- <code>$this->db->like('title', 'match');
- <br /><br />// Produces: WHERE title LIKE '%match%' </code>
-
- <p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
- <code>$this->db->like('title', 'match');<br />
- $this->db->like('body', 'match');
- <br /><br />
- // WHERE title LIKE '%match%' AND body LIKE '%match%</code>
- If you want to control where the wildcard (%) is placed, you can use an optional third argument. Your options are 'before', 'after' and 'both' (which is the default).
- <code>$this->db->like('title', 'match', 'before');
- <br />
- // Produces: WHERE title LIKE '%match' <br />
- <br />
- $this-&gt;db-&gt;like('title', 'match', 'after'); <br />
-// Produces: WHERE title LIKE 'match%' <br />
-<br />
- $this-&gt;db-&gt;like('title', 'match', 'both'); <br />
-// Produces: WHERE title LIKE '%match%' </code> </li>
-
-If you do not want to use the wildcard (%) you can pass to the optional third argument the option 'none'.
-
-<code>
- $this-&gt;db-&gt;like('title', 'match', 'none'); <br />
-// Produces: WHERE title LIKE 'match'
-</code>
-
- <li><strong>Associative array method:</strong>
-
- <code>
- $array = array('title' => $match, 'page1' => $match, 'page2' => $match);<br /><br />
-
- $this->db->like($array);
- <br /><br />// WHERE title LIKE '%match%' AND page1 LIKE '%match%' AND page2 LIKE '%match%'</code></li>
- </ol>
-
-
-<h2>$this->db->or_like();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->like('title', 'match');<br />
-$this->db->or_like('body', $match);
-<br />
-<br />// WHERE title LIKE '%match%' OR body LIKE '%match%'</code>
-
-
-
-
-<p class="important">Note: or_like() was formerly known as orlike(), which has been removed.</p>
-<h2>$this-&gt;db-&gt;not_like();</h2>
-<p>This function is identical to <strong>like()</strong>, except that it generates NOT LIKE statements:</p>
-<code> $this-&gt;db-&gt;not_like('title', 'match');<br />
-<br />
-// WHERE title NOT LIKE '%match%</code>
-<h2>$this-&gt;db-&gt;or_not_like();</h2>
-<p>This function is identical to <strong>not_like()</strong>, except that multiple instances are joined by OR:</p>
-<code> $this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;or_not_like('body', 'match'); <br />
-<br />
-// WHERE title LIKE '%match% OR body NOT LIKE '%match%'</code>
-<h2>$this->db->group_by();</h2>
-<p>Permits you to write the GROUP BY portion of your query:</p>
-
-<code>$this->db->group_by("title");
-<br /><br />// Produces: GROUP BY title
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-<code>$this->db->group_by(array("title", "date"));
-<br />
-<br />// Produces: GROUP BY title, date</code>
-
-<p class="important">Note: group_by() was formerly known as groupby(), which has been removed. </p>
-
-<h2> $this-&gt;db-&gt;distinct();<br />
-</h2>
-<p>Adds the &quot;DISTINCT&quot; keyword to a query</p>
-<p><code>$this-&gt;db-&gt;distinct();<br />
- $this-&gt;db-&gt;get('table');<br />
- <br />
- // Produces: SELECT DISTINCT * FROM table</code></p>
-<h2>$this->db->having();</h2>
-<p>Permits you to write the HAVING portion of your query. There are 2 possible syntaxes, 1 argument or 2:</p>
-
-<code>$this->db->having('user_id = 45');
-<br />
-// Produces: HAVING user_id = 45<br />
-<br />
-$this-&gt;db-&gt;having('user_id', 45); <br />
-// Produces: HAVING user_id = 45<br />
-<br />
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-
-<p><code>$this->db->having(array('title =' => 'My Title', 'id <' => $id)); <br />
- <br />
- // Produces: HAVING title = 'My Title', id < 45</code></p>
-<p>If you are using a database that CodeIgniter escapes queries for, you can prevent escaping content by passing an optional third argument, and setting it to FALSE.</p>
-<p><code>$this-&gt;db-&gt;having('user_id', 45); <br />
-// Produces: HAVING `user_id` = 45 in some databases such as MySQL
- <br />
- $this-&gt;db-&gt;having('user_id', 45, FALSE); <br />
-// Produces: HAVING user_id = 45</code></p>
-<h2>$this-&gt;db-&gt;or_having();</h2>
-<p>Identical to having(), only separates multiple clauses with &quot;OR&quot;.</p>
-<h2>$this->db->order_by();</h2>
-<p>Lets you set an ORDER BY clause. The first parameter contains the name of the column you would like to order by.
-The second parameter lets you set the direction of the result. Options are <kbd>asc</kbd> or <kbd>desc</kbd>, or <kbd>random</kbd>. </p>
-
-<code>$this->db->order_by("title", "desc");
-<br />
-<br />// Produces: ORDER BY title DESC
-</code>
-
-<p>You can also pass your own string in the first parameter:</p>
-
-<code>$this->db->order_by('title desc, name asc');
-<br />
-<br />// Produces: ORDER BY title DESC, name ASC
-</code>
-
-<p>Or multiple function calls can be made if you need multiple fields.</p>
-
-<p><code>$this->db->order_by("title", "desc");<br />
- $this->db->order_by("name", "asc"); <br />
- <br />
- // Produces: ORDER BY title DESC, name ASC
- </code></p>
-<p class="important">Note: order_by() was formerly known as orderby(), which has been removed.</p>
-<p class="important">Note: random ordering is not currently supported in Oracle or MSSQL drivers. These will default to 'ASC'.</p>
-<h2>$this->db->limit();</h2>
-<p>Lets you limit the number of rows you would like returned by the query:</p>
-
-<code>
-$this->db->limit(10);<br />
-<br />
-// Produces: LIMIT 10</code>
-
-
-<p>The second parameter lets you set a result offset.</p>
-
-<code>
-$this->db->limit(10, 20);<br />
-<br />
-// Produces: LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)</code>
-
-
-<h2>$this->db->count_all_results();</h2>
-
-<p>Permits you to determine the number of rows in a particular Active Record query. Queries will accept Active Record restrictors such as where(), or_where(), like(), or_like(), etc. Example:</p>
-<code>echo $this->db->count_all_results('<var>my_table</var>');<br />
-
-// Produces an integer, like 25<br />
-<br />
-$this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;from('<var>my_table</var>');<br />
-echo $this-&gt;db-&gt;count_all_results();<br />
-// Produces an integer, like 17 </code>
-
-<h2>$this->db->count_all();</h2>
-
-<p>Permits you to determine the number of rows in a particular table. Submit the table name in the first parameter. Example:</p>
-
-<code>echo $this->db->count_all('<var>my_table</var>');<br />
-<br />
-// Produces an integer, like 25</code>
-
-
-
-<a name="insert">&nbsp;</a>
-<h1>Inserting Data</h1>
-
-<h2>$this->db->insert();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p>Here is an example using an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->insert('mytable', $object);
-<br /><br />
-// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')</code>
-
-<p>The first parameter will contain the table name, the second is an object.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<h2>$this->db->insert_batch();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date'<br />
-&nbsp;&nbsp;&nbsp;)<br />
-);<br />
-<br />
-$this->db->insert_batch('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'), ('Another title', 'Another name', 'Another date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-
-
-<h2>$this->db->set();</h2>
-<p>This function enables you to set values for <dfn>inserts</dfn> or <dfn>updates</dfn>.</p>
-
-<p><strong>It can be used instead of passing a data array directly to the insert or update functions:</strong> </p>
-
-<code>$this->db->set('name', $name);
-<br />
-$this->db->insert('mytable');
-<br /><br />
-// Produces: INSERT INTO mytable (name) VALUES ('{$name}')</code>
-
-<p>If you use multiple function called they will be assembled properly based on whether you are doing an insert or an update:</p>
-
-<code>$this-&gt;db-&gt;set('name', $name);<br />
-$this-&gt;db-&gt;set('title', $title);<br />
-$this-&gt;db-&gt;set('status', $status);<br />
-$this-&gt;db-&gt;insert('mytable'); </code>
-<p><strong>set()</strong> will also accept an optional third parameter ($escape), that will prevent data from being escaped if set to FALSE. To illustrate the difference, here is set() used both with and without the escape parameter.</p>
-<p><code>$this-&gt;db-&gt;set('field', 'field+1', FALSE);<br />
- $this-&gt;db-&gt;insert('mytable'); <br />
- // gives INSERT INTO mytable (field) VALUES (field+1)<br />
- <br />
- $this-&gt;db-&gt;set('field', 'field+1');<br />
- $this-&gt;db-&gt;insert('mytable'); <br />
- // gives INSERT INTO mytable (field) VALUES ('field+1')</code></p>
-<p>You can also pass an associative array to this function:</p>
-<code>
-$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
-$this->db->set($array);<br />
-$this->db->insert('mytable');
-</code>
-
-<p>Or an object:</p>
-
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->set($object);<br />
-$this->db->insert('mytable');
-</code>
-
-
-
-<a name="update">&nbsp;</a>
-<h1>Updating Data</h1>
-
-<h2>$this->db->update();</h2>
-<p>Generates an update string and runs the query based on the data you supply. You can pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using
-an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $data);
-<br /><br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-<p>Or you can supply an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $object);
-<br />
-<br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<p>You'll notice the use of the <dfn>$this->db->where()</dfn> function, enabling you to set the WHERE clause.
-You can optionally pass this information directly into the update function as a string:</p>
-
-<code>$this->db->update('mytable', $data, "id = 4");</code>
-
-<p>Or as an array:</p>
-
-<code>$this->db->update('mytable', $data, array('id' => $id));</code>
-
-<p>You may also use the <dfn>$this->db->set()</dfn> function described above when performing updates.</p>
-
-<h2>$this->db->update_batch();</h2>
-<p>Generates an update string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using an array:</p>
-
-<code>
-$data = array(<br/>
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name 2' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date 2'<br />
-&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name 2' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date 2'<br />
-&nbsp;&nbsp;&nbsp;)<br/>
-);<br />
-<br />
-$this->db->update_batch('mytable', $data, 'title');
-<br /><br />
-// Produces: <br />
-// UPDATE `mytable` SET `name` = CASE<br />
-// WHEN `title` = 'My title' THEN 'My Name 2'<br />
-// WHEN `title` = 'Another title' THEN 'Another Name 2'<br />
-// ELSE `name` END,<br />
-// `date` = CASE <br />
-// WHEN `title` = 'My title' THEN 'My date 2'<br />
-// WHEN `title` = 'Another title' THEN 'Another date 2'<br />
-// ELSE `date` END<br />
-// WHERE `title` IN ('My title','Another title')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values, the third parameter is the where key.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-
-<a name="delete">&nbsp;</a>
-<h1>Deleting Data</h1>
-
-
-
-<h2>$this->db->delete();</h2>
-<p>Generates a delete SQL string and runs the query.</p>
-
-<code>
-$this->db->delete('mytable', array('id' => $id));
-<br /><br />
-// Produces:<br />
-// DELETE FROM mytable <br />
-// WHERE id = $id</code>
-
-<p>The first parameter is the table name, the second is the where clause. You can also use the <dfn>where()</dfn> or <dfn>or_where()</dfn> functions instead of passing
-the data to the second parameter of the function:</p>
-
-<p><code> $this->db->where('id', $id);<br />
- $this->db->delete('mytable'); <br />
- <br />
- // Produces:<br />
- // DELETE FROM mytable <br />
- // WHERE id = $id</code></p>
-<p>An array of table names can be passed into delete() if you would like to delete data from more than 1 table.</p>
-<p><code>$tables = array('table1', 'table2', 'table3');<br />
-$this-&gt;db-&gt;where('id', '5');<br />
-$this-&gt;db-&gt;delete($tables);</code></p>
-<p>If you want to delete all data from a table, you can use the <dfn>truncate()</dfn> function, or <dfn>empty_table()</dfn>.</p>
-<h2>$this-&gt;db-&gt;empty_table();</h2>
-<p>Generates a delete SQL string and runs the query.<code> $this-&gt;db-&gt;empty_table('mytable'); <br />
- <br />
-// Produces<br />
-// DELETE FROM mytable</code></p>
-<h2>$this-&gt;db-&gt;truncate();</h2>
-<p>Generates a truncate SQL string and runs the query.</p>
-<code> $this-&gt;db-&gt;from('mytable'); <br />
-$this-&gt;db-&gt;truncate(); <br />
-// or <br />
-$this-&gt;db-&gt;truncate('mytable'); <br />
-<br />
-// Produce:<br />
-// TRUNCATE mytable <br />
-</code>
-<p class="important"><strong>Note:</strong> If the TRUNCATE command isn't available, truncate() will execute as &quot;DELETE FROM table&quot;.</p>
-
-<h1><a name="chaining">&nbsp;</a>Method Chaining</h1>
-
-<p>Method chaining allows you to simplify your syntax by connecting multiple functions. Consider this example:</p>
-
-<code>
-<dfn>$this->db</dfn><kbd>-></kbd><var>select</var>('title')<kbd>-></kbd><var>from</var>('mytable')<kbd>-></kbd><var>where</var>('id', $id)<kbd>-></kbd><var>limit</var>(10, 20);<br />
-<br />
-$query = $this->db->get();</code>
-
-<p class="important"><strong>Note:</strong> Method chaining only works with PHP 5.</p>
-
-<p>&nbsp;</p>
-
-<h1><a name="caching">&nbsp;</a>Active Record Caching</h1>
-
-<p>While not &quot;true&quot; caching, Active Record enables you to save (or &quot;cache&quot;) certain parts of your queries for reuse at a later point in your script's execution. Normally, when an Active Record call is completed, all stored information is reset for the next call. With caching, you can prevent this reset, and reuse information easily.</p>
-
-<p>Cached calls are cumulative. If you make 2 cached select() calls, and then 2 uncached select() calls, this will result in 4 select() calls. There are three Caching functions available:</p>
-
-<h2>$this-&gt;db-&gt;start_cache()</h2>
-
-<p>This function must be called to begin caching. All Active Record queries of the correct type (see below for supported queries) are stored for later use.</p>
-
-<h2>$this-&gt;db-&gt;stop_cache()</h2>
-
-<p>This function can be called to stop caching.</p>
-
-<h2>$this-&gt;db-&gt;flush_cache()</h2>
-
-<p>This function deletes all items from the Active Record cache.</p>
-
-<p>Here's a usage example:</p>
-
-<p><code>$this-&gt;db-&gt;start_cache();<br />
-$this-&gt;db-&gt;select('field1');<br />
-$this-&gt;db-&gt;stop_cache();<br /><br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates: SELECT `field1` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates: SELECT `field1`, `field2` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;flush_cache();<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates: SELECT `field2` FROM (`tablename`)</code></p>
-
-<p class="important"> <strong>Note:</strong> The following statements can be cached: select, from, join, where, like, group_by, having, order_by, set</p>

-<h1>Database Caching Class</h1>
-
-<p>The Database Caching Class permits you to cache your queries as text files for reduced database load.</p>
-
-<p class="important"><strong>Important:</strong>&nbsp; This class is initialized automatically by the database driver
-when caching is enabled. Do NOT load this class manually.<br /><br />
-
-<strong>Also note:</strong>&nbsp; Not all query result functions are available when you use caching. Please read this page carefully.</p>
-
-<h2>Enabling Caching</h2>
-
-<p>Caching is enabled in three steps:</p>
-
-<ul>
-<li>Create a writable directory on your server where the cache files can be stored.</li>
-<li>Set the path to your cache folder in your <dfn>application/config/database.php</dfn> file.</li>
-<li>Enable the caching feature, either globally by setting the preference in your <dfn>application/config/database.php</dfn> file, or manually as described below.</li>
-</ul>
-
-<p>Once enabled, caching will happen automatically whenever a page is loaded that contains database queries.</p>
-
-
-<h2>How Does Caching Work?</h2>
-
-<p>CodeIgniter's query caching system happens dynamically when your pages are viewed.
-When caching is enabled, the first time a web page is loaded, the query result object will
-be serialized and stored in a text file on your server. The next time the page is loaded the cache file will be used instead of
-accessing your database. Your database usage can effectively be reduced to zero for any pages that have been cached.</p>
-
-<p>Only <dfn>read-type</dfn> (SELECT) queries can be cached, since these are the only type of queries that produce a result.
-<dfn>Write-type</dfn> (INSERT, UPDATE, etc.) queries, since they don't generate a result, will not be cached by the system.</p>
-
-<p>Cache files DO NOT expire. Any queries that have been cached will remain cached until you delete them. The caching system
-permits you clear caches associated with individual pages, or you can delete the entire collection of cache files.
-Typically you'll want to use the housekeeping functions described below to delete cache files after certain
-events take place, like when you've added new information to your database.</p>
-
-<h2>Will Caching Improve Your Site's Performance?</h2>
-
-<p>Getting a performance gain as a result of caching depends on many factors.
-If you have a highly optimized database under very little load, you probably won't see a performance boost.
-If your database is under heavy use you probably will see an improved response, assuming your file-system is not
-overly taxed. Remember that caching simply changes how your information is retrieved, shifting it from being a database
-operation to a file-system one.</p>
-
-<p>In some clustered server environments, for example, caching may be detrimental since file-system operations are so intense.
-On single servers in shared environments, caching will probably be beneficial. Unfortunately there is no
-single answer to the question of whether you should cache your database. It really depends on your situation.</p>
-
-<h2>How are Cache Files Stored?</h2>
-
-<p>CodeIgniter places the result of EACH query into its own cache file. Sets of cache files are further organized into
-sub-folders corresponding to your controller functions. To be precise, the sub-folders are named identically to the
-first two segments of your URI (the controller class name and function name).</p>
-
-<p>For example, let's say you have a controller called <dfn>blog</dfn> with a function called <dfn>comments</dfn> that
-contains three queries. The caching system will create a cache folder
-called <kbd>blog+comments</kbd>, into which it will write three cache files.</p>
-
-<p>If you use dynamic queries that change based on information in your URI (when using pagination, for example), each instance of
-the query will produce its own cache file. It's possible, therefore, to end up with many times more cache files than you have
-queries.</p>
-
-
-<h2>Managing your Cache Files</h2>
-
-<p>Since cache files do not expire, you'll need to build deletion routines into your application. For example, let's say you have a blog
-that allows user commenting. Whenever a new comment is submitted you'll want to delete the cache files associated with the
-controller function that serves up your comments. You'll find two delete functions described below that help you
-clear data.</p>
-
-
-<h2>Not All Database Functions Work with Caching</h2>
-
-<p>Lastly, we need to point out that the result object that is cached is a simplified version of the full result object. For that reason,
-some of the query result functions are not available for use.</p>
-
-<p>The following functions <kbd>ARE NOT</kbd> available when using a cached result object:</p>
-
-<ul>
-<li>num_fields()</li>
-<li>field_names()</li>
-<li>field_data()</li>
-<li>free_result()</li>
-</ul>
-
-<p>Also, the two database resources (result_id and conn_id) are not available when caching, since result resources only
-pertain to run-time operations.</p>
-
-
-<br />
-
-<h1>Function Reference</h1>
-
-
-
-<h2>$this->db->cache_on()&nbsp; / &nbsp; $this->db->cache_off()</h2>
-
-<p>Manually enables/disables caching. This can be useful if you want to
-keep certain queries from being cached. Example:</p>
-
-<code>
-// Turn caching on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-// Turn caching off for this one query<br />
-$this->db->cache_off();<br />
-$query = $this->db->query("SELECT * FROM members WHERE member_id = '$current_user'");<br />
-<br />
-// Turn caching back on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM another_table");
-</code>
-
-
-<h2>$this->db->cache_delete()</h2>
-
-<p>Deletes the cache files associated with a particular page. This is useful if you need to clear caching after you update your database.</p>
-
-<p>The caching system saves your cache files to folders that correspond to the URI of the page you are viewing. For example, if you are viewing
-a page at <dfn>example.com/index.php/blog/comments</dfn>, the caching system will put all cache files associated with it in a folder
-called <dfn>blog+comments</dfn>. To delete those particular cache files you will use:</p>
-
-<code>$this->db->cache_delete('blog', 'comments');</code>
-
-<p>If you do not use any parameters the current URI will be used when determining what should be cleared.</p>
-
-
-<h2>$this->db->cache_delete_all()</h2>
-
-<p>Clears all existing cache files. Example:</p>
-
-<code>$this->db->cache_delete_all();</code>

-<h1>Custom Function Calls</h1>
-
-<h2>$this->db->call_function();</h2>
-
-<p>This function enables you to call PHP database functions that are not natively included in CodeIgniter, in a platform independent manner.
-For example, lets say you want to call the <dfn>mysql_get_client_info()</dfn> function, which is <strong>not</strong> natively supported
-by CodeIgniter. You could do so like this:
-</p>
-
-<code>$this->db->call_function('<var>get_client_info</var>');</code>
-
-<p>You must supply the name of the function, <strong>without</strong> the <var>mysql_</var> prefix, in the first parameter. The prefix is added
-automatically based on which database driver is currently being used. This permits you to run the same function on different database platforms.
-Obviously not all function calls are identical between platforms, so there are limits to how useful this function can be in terms of portability.</p>
-
-<p>Any parameters needed by the function you are calling will be added to the second parameter.</p>
-
-<code>$this->db->call_function('<var>some_function</var>', $param1, $param2, etc..);</code>
-
-
-<p>Often, you will either need to supply a database connection ID or a database result ID. The connection ID can be accessed using:</p>
-
-<code>$this->db->conn_id;</code>
-
-<p>The result ID can be accessed from within your result object, like this:</p>
-
-<code>$query = $this->db->query("SOME QUERY");<br />
-<br />
-<var>$query->result_id;</var></code>

-<h1>Database Configuration</h1>
-
-<p>CodeIgniter has a config file that lets you store your database connection values (username, password, database name, etc.).
-The config file is located at <samp>application/config/database.php</samp>. You can also set database connection values for specific <a href="../libraries/config.html">environments</a> by placing <strong>database.php</strong> it the respective environment config folder.</p>
-
-<p>The config settings are stored in a multi-dimensional array with this prototype:</p>
-
-<code>$db['default']['hostname'] = "localhost";<br />
-$db['default']['username'] = "root";<br />
-$db['default']['password'] = "";<br />
-$db['default']['database'] = "database_name";<br />
-$db['default']['dbdriver'] = "mysql";<br />
-$db['default']['dbprefix'] = "";<br />
-$db['default']['pconnect'] = TRUE;<br />
-$db['default']['db_debug'] = FALSE;<br />
-$db['default']['cache_on'] = FALSE;<br />
-$db['default']['cachedir'] = &quot;&quot;;<br />
-$db['default']['char_set'] = "utf8";<br />
-$db['default']['dbcollat'] = "utf8_general_ci";<br />
-$db['default']['swap_pre'] = "";<br />
-$db['default']['autoinit'] = TRUE;<br />
-$db['default']['stricton'] = FALSE;</code>
-
-<p>The reason we use a multi-dimensional array rather than a more simple one is to permit you to optionally store
-multiple sets of connection values. If, for example, you run multiple environments (development, production, test, etc.)
-under a single installation, you can set up a connection group for each, then switch between groups as needed.
-For example, to set up a "test" environment you would do this:</p>
-
-<code>$db['test']['hostname'] = "localhost";<br />
-$db['test']['username'] = "root";<br />
-$db['test']['password'] = "";<br />
-$db['test']['database'] = "database_name";<br />
-$db['test']['dbdriver'] = "mysql";<br />
-$db['test']['dbprefix'] = "";<br />
-$db['test']['pconnect'] = TRUE;<br />
-$db['test']['db_debug'] = FALSE;<br />
-$db['test']['cache_on'] = FALSE;<br />
-$db['test']['cachedir'] = &quot;&quot;;<br />
-$db['test']['char_set'] = "utf8";<br />
-$db['test']['dbcollat'] = "utf8_general_ci";<br />
-$db['test']['swap_pre'] = "";<br />
-$db['test']['autoinit'] = TRUE;<br />
-$db['test']['stricton'] = FALSE;</code>
-
-
-<p>Then, to globally tell the system to use that group you would set this variable located in the config file:</p>
-
-<code>$active_group = "test";</code>
-
-<p>Note: The name "test" is arbitrary. It can be anything you want. By default we've used the word "default"
-for the primary connection, but it too can be renamed to something more relevant to your project.</p>
-
-<h3>Active Record</h3>
-
-<p>The <a href="active_record.html">Active Record Class</a> is globally enabled or disabled by setting the $active_record variable in the database configuration file to TRUE/FALSE (boolean). If you are not using the active record class, setting it to FALSE will utilize fewer resources when the database classes are initialized.</p>
-
-<code>$active_record = TRUE;</code>
-
-<p class="important"><strong>Note:</strong> that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.</p>
-
-<h3>Explanation of Values:</h3>
-
-<ul>
-<li><strong>hostname</strong> - The hostname of your database server. Often this is "localhost".</li>
-<li><strong>username</strong> - The username used to connect to the database.</li>
-<li><strong>password</strong> - The password used to connect to the database.</li>
-<li><strong>database</strong> - The name of the database you want to connect to.</li>
-<li><strong>dbdriver</strong> - The database type. ie: mysql, postgres, odbc, etc. Must be specified in lower case.</li>
-<li><strong>dbprefix</strong> - An optional table prefix which will added to the table name when running <a href="active_record.html">Active Record</a> queries. This permits multiple CodeIgniter installations to share one database.</li>
-<li><strong>pconnect</strong> - TRUE/FALSE (boolean) - Whether to use a persistent connection.</li>
-<li><strong>db_debug</strong> - TRUE/FALSE (boolean) - Whether database errors should be displayed.</li>
-<li><strong>cache_on</strong> - TRUE/FALSE (boolean) - Whether database query caching is enabled, see also <a href="caching.html">Database Caching Class</a>.</li>
-<li><strong>cachedir</strong> - The absolute server path to your database query cache directory.</li>
-<li><strong>char_set</strong> - The character set used in communicating with the database.</li>
-<li><strong>dbcollat</strong> - The character collation used in communicating with the database. <p class="important"><strong>Note:</strong> For MySQL and MySQLi databases, this setting is only used as a backup if your server is running PHP &lt; 5.2.3 or MySQL &lt; 5.0.7 (and in table creation queries made with DB Forge). There is an incompatibility in PHP with mysql_real_escape_string() which can make your site vulnerable to SQL injection if you are using a multi-byte character set and are running versions lower than these. Sites using Latin-1 or UTF-8 database character set and collation are unaffected.</p></li>
-<li><strong>swap_pre</strong> - A default table prefix that should be swapped with <var>dbprefix</var>. This is useful for distributed applications where you might run manually written queries, and need the prefix to still be customizable by the end user.</li>
-<li><strong>autoinit</strong> - Whether or not to automatically connect to the database when the library loads. If set to false, the connection will take place prior to executing the first query.</li>
-<li><strong>stricton</strong> - TRUE/FALSE (boolean) - Whether to force "Strict Mode" connections, good for ensuring strict SQL while developing an application.</li>
-<li><strong>port</strong> - The database port number. To use this value you have to add a line to the database config array.<code>$db['default']['port'] = 5432;</code>
-</ul>
-
-<p class="important"><strong>Note:</strong> Depending on what database platform you are using (MySQL, Postgres, etc.)
-not all values will be needed. For example, when using SQLite you will not need to supply a username or password, and
-the database name will be the path to your database file. The information above assumes you are using MySQL.</p>

-<p>The "auto connect" feature will load and instantiate the database class with every page load.
-To enable "auto connecting", add the word <var>database</var> to the library array, as indicated in the following file:</p>
-
-<p><kbd>application/config/autoload.php</kbd></p>
-
-<h2>Manually Connecting</h2>
-
-<p>If only some of your pages require database connectivity you can manually connect to your database by adding this
-line of code in any function where it is needed, or in your class constructor to make the database
-available globally in that class.</p>
-
-<code>$this->load->database();</code>
-
-<p class="important">If the above function does <strong>not</strong> contain any information in the first parameter it will connect
-to the group specified in your database config file. For most people, this is the preferred method of use.</p>
-
-<h3>Available Parameters</h3>
-
-<ol>
- <li>The database connection values, passed either as an array or a DSN string.</li>
- <li>TRUE/FALSE (boolean). Whether to return the connection ID (see Connecting to Multiple Databases below).</li>
- <li>TRUE/FALSE (boolean). Whether to enable the Active Record class. Set to TRUE by default.</li>
-</ol>
-
-
-<h3>Manually Connecting to a Database</h3>
-
-<p>The first parameter of this function can <strong>optionally</strong> be used to specify a particular database group
-from your config file, or you can even submit connection values for a database that is not specified in your config file.
-Examples:</p>
-
-<p>To choose a specific group from your config file you can do this:</p>
-
-<code>$this->load->database('<samp>group_name</samp>');</code>
-
-<p>Where <samp>group_name</samp> is the name of the connection group from your config file.</p>
-
-
-<p>To connect manually to a desired database you can pass an array of values:</p>
-
-<code>$config['hostname'] = "localhost";<br />
-$config['username'] = "myusername";<br />
-$config['password'] = "mypassword";<br />
-$config['database'] = "mydatabase";<br />
-$config['dbdriver'] = "mysql";<br />
-$config['dbprefix'] = "";<br />
-$config['pconnect'] = FALSE;<br />
-$config['db_debug'] = TRUE;<br />
-$config['cache_on'] = FALSE;<br />
-$config['cachedir'] = "";<br />
-$config['char_set'] = "utf8";<br />
-$config['dbcollat'] = "utf8_general_ci";<br />
-<br />
-$this->load->database(<samp>$config</samp>);</code>
-
-<p>For information on each of these values please see the <a href="configuration.html">configuration page</a>.</p>
-
-<p class="important"><strong>Note:</strong> For the PDO driver, $config['hostname'] should look like this: 'mysql:host=localhost'</p>
-
-<p>Or you can submit your database values as a Data Source Name. DSNs must have this prototype:</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<p>To override default config values when connecting with a DSN string, add the config variables as a query string.</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&amp;dbcollat=utf8_general_ci&amp;cache_on=true&amp;cachedir=/path/to/cache';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<h2>Connecting to Multiple Databases</h2>
-
-<p>If you need to connect to more than one database simultaneously you can do so as follows:</p>
-
-
-<code>$DB1 = $this->load->database('group_one', TRUE);<br />
-$DB2 = $this->load->database('group_two', TRUE);
-</code>
-
-<p>Note: Change the words "group_one" and "group_two" to the specific group names you are connecting to (or
-you can pass the connection values as indicated above).</p>
-
-<p>By setting the second parameter to TRUE (boolean) the function will return the database object.</p>
-
-<div class="important">
-<p>When you connect this way, you will use your object name to issue commands rather than the syntax used throughout this guide. In other words, rather than issuing commands with:</p>
-
-<p>$this->db->query();<br />$this->db->result();<br /> etc...</p>
-
-<p>You will instead use:</p>
-
-<p>$DB1->query();<br />$DB1->result();<br /> etc...</p>
-
-</div>
-
-<h2>Reconnecting / Keeping the Connection Alive</h2>
-
-<p>If the database server's idle timeout is exceeded while you're doing some heavy PHP lifting (processing an image, for instance), you should consider pinging the server by using the <dfn>reconnect()</dfn> method before sending further queries, which can gracefully keep the connection alive or re-establish it.</p>
-
-<code>$this->db->reconnect();</code>
-
-<h2>Manually closing the Connection</h2>
-
-<p>While CodeIgniter intelligently takes care of closing your database connections, you can explicitly close the connection.</p>
-
-<code>$this->db->close();</code>

-<h1>Database Quick Start: Example Code</h1>
-
-<p>The following page contains example code showing how the database class is used. For complete details please
-read the individual pages describing each function.</p>
-
-
-<h2>Initializing the Database Class</h2>
-
-<p>The following code loads and initializes the database class based on your <a href="configuration.html">configuration</a> settings:</p>
-
-<code>$this->load->database();</code>
-
-<p>Once loaded the class is ready to be used as described below.</p>
-
-<p>Note: If all your pages require database access you can connect automatically. See the <a href="connecting.html">connecting</a> page for details.</p>
-
-
-<h2>Standard Query With Multiple Results (Object Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->email;<br />
-}<br />
-<br />
-echo 'Total Results: ' . $query->num_rows();
-</code>
-
-<p>The above <dfn>result()</dfn> function returns an array of <strong>objects</strong>. Example: $row->title</p>
-
-
-<h2>Standard Query With Multiple Results (Array Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result_array() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['email'];<br />
-}</code>
-
-<p>The above <dfn>result_array()</dfn> function returns an array of standard array indexes. Example: $row['title']</p>
-
-
-<h2>Testing for Results</h2>
-
-<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test for a result first
-using the <dfn>num_rows()</dfn> function:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-<br />
-if ($query->num_rows() > 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
-&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-
-
-
-<h2>Standard Query With Single Result</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row();<br />
-echo $row->name;<br />
-</code>
-
-<p>The above <dfn>row()</dfn> function returns an <strong>object</strong>. Example: $row->name</p>
-
-
-<h2>Standard Query With Single Result (Array version)</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row_array();<br />
-echo $row['name'];<br />
-</code>
-
-<p>The above <dfn>row_array()</dfn> function returns an <strong>array</strong>. Example: $row['name']</p>
-
-
-<h2>Standard Insert</h2>
-
-<code>
-$sql = "INSERT INTO mytable (title, name) <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";<br />
-<br />
-$this->db->query($sql);<br />
-<br />
-echo $this->db->affected_rows();
-</code>
-
-
-
-
-<h2>Active Record Query</h2>
-
-<p>The <a href="active_record.html">Active Record Pattern</a> gives you a simplified means of retrieving data:</p>
-
-<code>
-$query = $this->db->get('table_name');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>The above <dfn>get()</dfn> function retrieves all the results from the supplied table.
-The <a href="active_record.html">Active Record</a> class contains a full compliment of functions
-for working with data.</p>
-
-
-<h2>Active Record Insert</h2>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')</code>

-<h1>Field Data</h1>
-
-
-<h2>$this->db->list_fields()</h2>
-<p>Returns an array containing the field names. This query can be called two ways:</p>
-
-
-<p>1. You can supply the table name and call it from the <dfn>$this->db-></dfn> object:</p>
-
-<code>
-$fields = $this->db->list_fields('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-<p>2. You can gather the field names associated with any query you run by calling the function
-from your query result object:</p>
-
-<code>
-$query = $this->db->query('SELECT * FROM some_table');
-<br /><br />
-
-foreach ($query->list_fields() as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-
-<h2>$this->db->field_exists()</h2>
-
-<p>Sometimes it's helpful to know whether a particular field exists before performing an action.
-Returns a boolean TRUE/FALSE. Usage example:</p>
-
-<code>
-if ($this->db->field_exists('field_name', 'table_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note: Replace <em>field_name</em> with the name of the column you are looking for, and replace
-<em>table_name</em> with the name of the table you are looking for.</p>
-
-
-<h2>$this->db->field_data()</h2>
-<p>Returns an array of objects containing field information.</p>
-<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
-
-
-<p class="important">Note: Not all databases provide meta-data.</p>
-
-<p>Usage example:</p>
-
-<code>
-$fields = $this->db->field_data('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field->name;<br />
-&nbsp;&nbsp;&nbsp;echo $field->type;<br />
-&nbsp;&nbsp;&nbsp;echo $field->max_length;<br />
-&nbsp;&nbsp;&nbsp;echo $field->primary_key;<br />
-}
-</code>
-
-<p>If you have run a query already you can use the result object instead of supplying the table name:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-$fields = $query->field_data();
-</code>
-
-
-<p>The following data is available from this function if supported by your database:</p>
-
-<ul>
-<li>name - column name</li>
-<li>max_length - maximum length of the column</li>
-<li>primary_key - 1 if the column is a primary key</li>
-<li>type - the type of the column</li>
-</ul>
