+

Squel.js

+

- lightweight Javascript library for building SQL query strings.

+

- usable with node.js and in the browser.

+

- well tested.

+
+ +
+

+ npm install squel +

+ +

Basic version

+

(~7 KB minified + gzipped)

+ + +

Basic + Database engines

+

(~8 KB minified + gzipped)

+ +
+ +
+ + +
+

Installation

 + +

Node.js

+ + 
npm install squel
+ +

Once done you can use require to access the API:

+ + 
var squel = require("squel");
+ +

Bower

+ + 
bower install squel
+ +

Browser

+ +

Include the following within your HTML body section, near the bottom:

+ + 
<script type="text/javascript" src="/your/path/to/squel.min.js"></script>
+ +

Once loaded the squel API will be available in the global object:

+ + 
log( squel.VERSION );    /* version string */
+ +

NOTE: It is recommended that you do NOT create queries browser-side to run on the + server as this massively increases your exposure to SQL Injection attacks.

+ +
+ +
+

Overview

 + +

Squel helps you quickly and easily build SQL query strings through an object oriented API. + There are two main benefits to using Squel to build your queries:

+ +
    +
  1. It requires less effort - instead of having to use brittle methods like string + concatenation and substitution you get a nice clean API to do the hard work for you.
    2. +
  2. It lets you build flexibly - Sometimes you don't yet know what your final query ought + to look like until you've checked information from various other parts of your program. Representing the + query as an object which can be manipulated allows you to be flexible about how you build it.
    3. +
+ +

Ok, now you're convinced! Before you get stuck in here are a few things to be aware of...

+ +

Squel uses method chaining to + make things easy. For example, instead of writing:

+ + 
+            var s = squel.select();
+            s.from("student");
+            log( s.toString() );    /* SELECT * FROM student */
+
+ +

Hint: You can run the example above by clicking it!

+ +

You can simply write:

+ + 
+            log( squel.select().from("students").toString() );  /* SELECT * FROM students */
+
+ + What's even better, the toString() method gets called automatically by the Javascript interpreter + whenever a string representation of an object is needed. So we can actually simplify the previous statement to: + + 
+            log( '' + squel.select().from("students") );  /* SELECT * FROM students */
+
+ +

Note: All of Squel's builders provide the toString() method. It is this + method which constructs the final query string.

+ +

Squel does not check to see if your final query is semantically correct (i.e. that it makes + sense). Your database engine already does a good enough job of that. On the plus side Squel allows you + to use proprietary database functions and other complex constructs:

+ + 
+            log(
+                squel.select({ separator: "\n" })
+                    .from("students")
+                    .field("name")
+                    .field("MIN(test_score)")
+                    .field("MAX(test_score)")
+                    .field("GROUP_CONCAT(DISTINCT test_score ORDER BY test_score DESC SEPARATOR ' ')")
+                    .group("name")
+                    .toString()
+            );
+            /*
+                SELECT
+                    name,
+                    MIN(test_score),
+                    MAX(test_score),
+                    GROUP_CONCAT(DISTINCT test_score ORDER BY test_score DESC SEPARATOR ' ')
+                FROM
+                    students
+                GROUP BY
+                    name
+            */
+
+ + + +
+ +
+

SELECT

 + +

To get an instance of the SELECT query builder:

+ + 
+            var q = squel.select();
+
+ +

The name of a table to fetch data from is provided:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .toString()
+            );
+            /* SELECT * FROM students */
+
+ +

Squel usually outputs a single line string, but you can use a different separator to change this look:

+ + 
+            log(
+                squel.select({ separator: "\n" })
+                    .from("students")
+                    .toString()
+            );
+            /*
+                SELECT
+                * 
+                FROM students
+            */
+
+ +

Multiple tables

+ +

You can select data from multiple tables and provide aliases where needed:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .from("lecturers", "l")
+                    .from("admins")
+                    .toString()
+            );
+            /* SELECT * FROM students, lecturers `l`, admins */
+
+ +

Sub-queries as tables

+ +

Instead of explicitly naming tables you can use SQL sub-queries as such:

+ + 
+            log(
+                squel.select()
+                    .from( squel.select().from('students'), 's' )
+                    .field('s.id')
+                    .toString()
+            );
+            /*  SELECT s.id FROM (SELECT * FROM students) `s` */
+
+ +

Fields

+ +

You can specify field names on their own or by the table they belong to:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .field("id")
+                    .field("students.name")
+                    .toString()
+            );
+            /* SELECT id, students.name FROM students */
+
+ +

Field names can be given aliases in order to customize the column names in the query results :

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .field("id", "Id")
+                    .field("students.name", "Student Name")
+                    .toString()
+            );
+            /* SELECT id AS "Id", students.name AS "Student Name" FROM students */
+
+ +

Database functions can be used in place of field names for more complex results:

+ + 
+            log(
+                squel.select()
+                    .from("students", "s")
+                    .field("s.id")
+                    .field("s.test_score", "Test score")
+                    .field("DATE_FORMAT(s.date_taken, '%M %Y')", "Taken on")
+                    .toString()
+            );
+            /*
+                SELECT
+                    s.id,
+                    s.test_score AS "Test score"
+                    DATE_FORMAT(s.date_taken, '%M %Y') AS "Taken on"
+                FROM
+                    students `s`
+            */
+
+ +

You can even use a sub-query as a field specifier:

+ + 
+            log(
+                squel.select()
+                    .from("students", "s")
+                    .field(squel.select().field("MAX(score)").from("scores"), 'score')
+                    .toString()
+            );
+            /*
+                SELECT
+                    (SELECT MAX(score) FROM scores) AS "score"
+                FROM
+                    students `s`
+            */
+
+ +

If you wish to obtain DISTINCT results you can do so:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .field("id")
+                    .distinct()
+                    .toString()
+            );
+            /*  SELECT DISTINCT id FROM students    */
+
+ +

Joins

+ +

Squel supports INNER, OUTER, LEFT and RIGHT joins. To do an + INNER join:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .join("teachers")
+                    .toString()
+            );
+            /*  SELECT * FROM students INNER JOIN teachers */
+
+ +

You can specify table aliases:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .join("teachers", "t")
+                    .outer_join("expelled")
+                    .toString()
+            );
+            /*  SELECT * FROM students
+                    INNER JOIN teachers `t`
+                    OUTER JOIN expelled
+            */
+
+ +

You can specify sub-queries:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .join(
+                        squel.select().field('score').from('results'),
+                        't'
+                    )
+                    .outer_join("expelled")
+                    .toString()
+            );
+            /*  SELECT * FROM students
+                    INNER JOIN (SELECT score FROM results) `t`
+                    OUTER JOIN expelled
+            */
+
+ +

And you can specify JOIN-ing conditions:

+ + 
+            log(
+                squel.select()
+                    .field("students.id")
+                    .from("students")
+                    .left_join("teachers", null, "students.id = teachers.student_id")
+                    .right_join("jailed", "j", "j.student_id = students.id")
+                    .toString()
+            );
+            /*  SELECT students.id FROM students
+                    LEFT JOIN teachers ON (students.id = teachers.student_id)
+                    RIGHT JOIN jailed `j` ON (j.student_id = students.id)
+            */
+
+ +

For an optional parameter such as an alias name, passing null is the same as omitting it.

+ +

You can also specify sub-queries in joins:

+ + 
+            log(
+                squel.select()
+                    .from('marks', 'm')
+                    .join( squel.select().from('students'), 's', 's.id = m.id' )
+                    .toString()
+            );
+            /*  SELECT * FROM marks `m` INNER JOIN (SELECT * FROM students) `s` ON (s.id = m.id) */
+
+ +

Filtering

+ + +

You can add WHERE clause filtering to your query very easily:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .where("name = 'Thomas'")
+                    .toString()
+            );
+            /*  SELECT id FROM students WHERE (name = 'Thomas')  */
+
+ +

Parameters substitution is supported:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .where("score = ?", squel.select().field('MAX(score)').from('scores'))
+                    .toString()
+            );
+            /*  SELECT id FROM students WHERE (score = (SELECT MAX(score) FROM scores))  */
+
+ + For more information on using parameterized queries see the parameters documentation section. + +

Multiple filters are automatically combined using AND:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .where("name = 'Thomas'")
+                    .where("age > 18")
+                    .toString()
+            );
+            /*  SELECT id FROM students WHERE (name = 'Thomas') AND (age > 18) */
+
+ +

Also filter using OR or any other operator you like:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .where("name = 'Thomas' OR age > 18")
+                    .where("id BETWEEN 200 and 300")
+                    .toString()
+            );
+            /*  SELECT id FROM students WHERE (name = 'Thomas' OR age > 18) AND (id BETWEEN 200 and 300) */
+
+ +

You can also pass in Expressions:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .where(
+                        squel.expr().and("name = 'Thomas'").or("age > 18")
+                    )
+                    .toString()
+            );
+            /*  SELECT id FROM students WHERE (name = 'Thomas' OR age > 18) */
+
+ +

Sorting

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .order("id")
+                    .order("name")
+                    .toString()
+            );
+            /*  SELECT id FROM students ORDER BY id ASC, name ASC */
+
+ +

Use the second argument of order() to change the direction of a sort:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .order("id")
+                    .order("name", false)  /* using TRUE instead would be the same as omitting it. */
+                    .toString()
+            );
+            /*  SELECT id FROM students ORDER BY id ASC, name DESC */
+
+ +

Additional arguments count as parameter values, e.g. for custom sort functions::

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .order("DIST(?, ?)", true, 1, 2)
+                    .toString()
+            );
+            /*  SELECT id FROM students ORDER BY DIST(1, 2) ASC */
+
+ +

Grouping

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .group("id")
+                    .toString()
+            );
+            /*  SELECT id FROM students GR0UP BY id */
+
+ +

Grouping on multiple fields is supported:

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .group("id")
+                    .group("students.name")
+                    .toString()
+            );
+            /*  SELECT id FROM students GR0UP BY id, students.name */
+
+ +

Having

+ + 
+            log(
+                squel.select()
+                    .field("id")
+                    .from("students")
+                    .group("id")
+                    .having("a = ?", 2)
+                    .toString()
+            );
+            /*  SELECT id FROM students GR0UP BY id HAVING (a = 2) */
+
+ +

Ranges

+ +

To LIMIT the number of results:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .limit(10)
+                    .toString()
+            );
+            /*  SELECT * FROM students LIMIT 10 */
+
+ +

To remove the previously set limit:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .limit(10)
+                    .limit(0)
+                    .toString()
+            );
+            /*  SELECT * FROM students */
+
+ +

To specify the OFFSET of the first row to return:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .offset(102)
+                    .toString()
+            );
+            /*  SELECT * FROM students OFFSET 102 */
+
+ +

Same as for limit(), you can remove a previously set offset:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .offset(1)
+                    .offset(0)
+                    .toString()
+            );
+            /*  SELECT * FROM students */
+
+ + +

Unions

+ + A simple UNION query: + + 
+            log(
+                squel.select()
+                    .from("students")
+                    .union( 
+                        squel.select()
+                            .from('scores') 
+                    )
+                    .union( 
+                        squel.select()
+                            .from('batches') 
+                    )
+                    .toString()
+            );
+            /*  SELECT * FROM students UNION (SELECT * FROM scores) UNION (SELECT * FROM batches) */
+
+ + + +

Scalar values and functions

+ + You can select a single string: + + 
+            log(
+                squel.select()
+                    .function('1')
+                    .toString()
+            );
+            /*  SELECT 1 */
+
+ + And this applies to database functions too: + + 
+            log(
+                squel.select()
+                    .function('MAX(?, ?)', 45, 87)
+                    .toString()
+            );
+            /*  SELECT MAX(45, 87) */
+
+ +
+ +
+

UPDATE

 + +

To get an instance of the UPDATE query builder:

+ + 
+            var q = squel.update();
+
+ +

You need to supply at least one table name and one field to update:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("name", "Thomas")
+                    .toString()
+            );
+            /*  UPDATE students SET name = "Thomas" */
+
+ +

Multiple table names can be supplied along with aliases:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .table("teachers", "t")
+                    .set("t.name", "Fred")
+                    .toString()
+            );
+            /*  UPDATE students, teachers `t` SET t.name = "Fred" */
+
+ +

Field values

+ +

Not all field values within a query need to be surrounded by quotes. Squel figures out how to represent each + field value based on its runtime type:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("name", "Fred")
+                    .set("age", 29)
+                    .set("score", 1.2)
+                    .set("graduate", false)
+                    .set("level", squel.select().field('MAX(level)').from('levels'))
+                    .toString()
+            );
+            /*  UPDATE students SET name = "Fred", age = 29, score = 1.2, graduate = FALSE, level = (SELECT MAX(level) FROM levels) */
+
+ +

You can turn off automatic quoting on a per-field basis:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("time", "GETDATE()", {
+                        dontQuote: true
+                    })
+                    .set("city", "London")
+                    .toString()
+            );
+            /*  UPDATE students SET time = GETDATE(), city = "London" */
+
+ +

You can even use NULL values:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("name", "Fred")
+                    .set("age", 29)
+                    .set("nickname", null)
+                    .toString()
+            );
+            /*  UPDATE students SET name = "Fred", age = 29, nickname = NULL */
+
+ +

Hint: Squel can also be configured to handle Object instances by registering custom value types.

+ +

If the second parameter to set() is not provided then the field name is assumed to be an operation:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("age = age + 1")
+                    .toString()
+            );
+            /*  UPDATE students SET age = age + 1 */
+
+ +

You can also set multiple fields in a single call:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .setFields({ age: 23, name: 'Fred' })
+                    .toString()
+            );
+            /*  UPDATE students SET age = 23, name = 'Fred' */
+
+ +

Parameter substitution for parameterized queries is also supported, see the section on Parameters.

+ +

Filtering, sorting and limits

+ +

The where(), order() and limit() methods are supported the same + way they are by the SELECT builder:

+ + 
+            log(
+                squel.update()
+                    .table("students")
+                    .set("name", "Fred")
+                    .set("age", 29)
+                    .where("id > 5")
+                    .where("id < 102")
+                    .order("id", false)
+                    .limit(5)
+                    .toString()
+            );
+            /*  UPDATE students SET name = "Fred", age = 29 WHERE (id > 5) AND (id < 102) ORDER BY id DESC LIMIT 5 */
+
+ +
+ +
+

DELETE

 + +

To get an instance of the DELETE query builder:

+ + 
+            var q = squel.delete();
+
+ +

You can also use the alias remove():

+ + 
+            var q = squel.remove();
+
+ +

You need to supply at least the table name:

+ + 
+            log(
+                squel.delete()
+                    .from("students")
+                    .toString()
+            );
+            /*  DELETE FROM students */
+
+ +

Joins

+ +

The join() and related methods are supported the same way + they are by the SELECT builder:

+ + 
+            log(
+                squel.delete()
+                    .from("students", "s")
+                    .outer_join("marks", "m", "m.student_id = s.id")
+                    .toString()
+            );
+            /*  DELETE FROM students `s` OUTER JOIN marks `m` ON (m.student_id = s.id) */
+
+ +

Filtering, sorting and limits

+ +

The where(), order() and limit() methods are supported the same way + they are by the SELECT builder:

+ + 
+            log(
+                squel.delete()
+                    .from("students")
+                    .where("id > 5")
+                    .where("id < 102")
+                    .order("id", false)
+                    .limit(5)
+                    .toString()
+            );
+            /*  DELETE FROM students WHERE (id > 5) AND (id < 102) ORDER BY id DESC LIMIT 5 */
+
+ +
+ +
+

INSERT

 + +

To get an instance of the INSERT query builder:

+ + 
+            var q = squel.insert();
+
+ +

At least the table name and one field must be supplied:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .set("name", "Thomas")
+                    .toString()
+            );
+            /*  INSERT INTO students (name) VALUES ("Thomas") */
+
+ +

Squel out how to treat each field value based on its runtime type:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .set("name", "Thomas")
+                    .set("age", 29)
+                    .set("score", 90.2)
+                    .set("graduate", true)
+                    .set("nickname", null)
+                    .set("level", squel.select().field('MAX(level)').from('levels'))
+                    .toString()
+            );
+            /*  INSERT INTO students (name, age, score, graduate, nickname, level) 
+                VALUES ('Thomas', 29, 90.2, TRUE, NULL, (SELECT MAX(level) FROM levels)) */
+
+ +

You can turn off automatic quoting on a per-field basis:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .set("time", "GETDATE()", {
+                        dontQuote: true
+                    })
+                    .set("city", "London")
+                    .toString()
+            );
+            /*  INSERT INTO students (time, city) VALUES(GETDATE(), "London") */
+
+ +

Multiple fields and rows

+ +

You can set multiple fields in a single call:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .setFields({ name: "Thomas", age: 29 })
+                    .toString()
+            );
+            /*  INSERT INTO students (name, age) VALUES ('Thomas', 29) */
+
+ +

You can even do a multi-row insert:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .setFieldsRows([
+                      { name: "Thomas", age: 29 },
+                      { name: "Jane", age: 31 }
+                    ])
+                    .toString()
+            );
+            /*  INSERT INTO students (name, age) VALUES ('Thomas', 29), ('Jane', 31) */
+
+ + Note: When doing a multi-row insertion every row specified in the parameter to setFieldsRows should + have the same field names specified. Squel will throw an error if this is not the case. + +

Other types

+ +

Insert from a selection result:

+ + 
+        log(
+            squel.insert()
+                .into("students")
+                .fromQuery( 
+                    ['username'], 
+                    squel.select().field('name').from('candidates') 
+                )
+                .toString()
+        );
+        /*  INSERT INTO students (username) (SELECT name FROM candidates) */
+
+ +
+ +
+

Parameters

 + +

+ Squel makes it very easy to build and use parameterized queries. Every query builder provides a + toParam() method which gives you a final query string separate to any parameters values previously passed in: +

+ + + 
+        log(
+          squel.select()
+            .from("students")
+            .where("a = ? AND b = ?", "test", true)
+            .order("CALC(?, ?)", true, 1.2, false)
+            .toParam()
+        );
+
+        /*
+          {
+            text:  SELECT * FROM students WHERE (a = ? AND b = ?) ORDER BY CALC(?, ?) ASC,
+            values:  [ 'test', true, 1.2, false ]
+          }
+        */
+
+ +

Using sub-queries as parameter values:

+ + 
+            log(
+              squel.select()
+                .from("students")
+                .where("a = ? AND b IN ?", "test", squel.select().field('score').from('results').where('c IN ?', [5, 6, 7]))
+                .toParam()
+            );
+
+            /*
+              {
+                text:  SELECT * FROM students WHERE (a = ? AND b IN (SELECT score FROM results WHERE c IN (?, ?, ?)))),
+                values:  [ 'test', 5, 6, 7 ]
+              }
+            */
+
+ +

A more complex example involving sub-queries and unions:

+ + 
+            log(
+              squel.select()
+                .from("students")
+                .where("a IN ?", squel.select().field('score').from('results').where('c = ?', 5))
+                .union(
+                    squel.select().field('age').from('states').where('person = ?', 
+                        squel.select().field('id').from('students').where('name = ?', 'John').limit(1)
+                    )
+                )
+                .toParam()
+            );
+
+            /*
+              {
+                text:  SELECT * FROM students WHERE (a IN (SELECT score FROM results WHERE (c = ?))) UNION (SELECT age FROM states WHERE (person = (SELECT id FROM students WHERE (name = ?) LIMIT 1))),
+                values:  [ 5, 'John' ]
+              }
+            */
+
+ +

As you can see the parameter values are not specially formatted as they normally are when toString() + is called. Also note that the parameter placeholders are non-numbered by default. To enable numbering use the + numberedParameters option:

+ + 
+        log(
+          squel.insert({ numberedParameters: true })
+            .into("students")
+            .set("a", "test")
+            .set("b", 1)
+            .set("c", null)
+            .toParam()
+        );
+
+        /*
+          {
+            text:  INSERT INTO students (a, b, c) VALUES ($1, $2, $3)
+            values:  [ 'test', 1, null ]
+          }
+        */
+
+ + Note: For the Postgres flavour numbered parameters are enabled by default. + +

You can change the start number:

+ + 
+        log(
+          squel.insert()
+            .into("students")
+            .set("a", "test")
+            .set("b", 1)
+            .set("c", null)
+            .toParam({ numberedParameters: true, numberedParametersStartAt: 3 })
+        );
+
+        /*
+          {
+            text:  INSERT INTO students (a, b, c) VALUES ($3, $4, $5)
+            values:  [ 'test', 1, null ]
+          }
+        */
+
+ + +

The values array returned is always flat, even for multi-row inserts:

+ + 
+            log(
+                squel.insert()
+                    .into("students")
+                    .setFieldsRows([
+                      { name: "Thomas", age: 29 },
+                      { name: "Jane", age: 31 }
+                    ])
+                    .toParam()
+            );
+            /*
+              {
+                text:  INSERT INTO students (name, age) VALUES (?, ?), (?, ?)
+                values:  [ 'Thomas', 29, 'Jane', 31 ]
+              }
+            */
+
+ + +

Array values can be used to create IN clauses:

+ + 
+          log(
+              squel.select()
+                  .field("id")
+                  .from("students")
+                  .where("age IN ?", [18, 19, 20])
+                  .toParam()
+          );
+
+          /*
+            {
+              text:  SELECT id FROM students WHERE (age IN (?, ?, ?)),
+              values: [ 18, 19, 20 ]
+            }
+          */
+
+ +

In general it is better to use toParam() rather than toString() when constructing the final query + as it gives you the opportunity to use your database engine methods to safely escape and interpolate your parameters.

+ +

Functions as values

+ +

Sometimes you may wish to use SQL functions as parameter values, e.g.:

+ + 
+          log(
+              squel.update()
+                .table('students')
+                .set('modified', 'NOW()')
+                .toString()
+          );
+
+          /*   UPDATE students SET modified = 'NOW()'   */
+
+ +

As you can see Squel automatically adds quotes since it treats the value as a string. To workaround this you can use the + .str() method:

p> + + 
+          log(
+              squel.update()
+                .table('students')
+                .set('modified', squel.str('NOW()'))
+                .toString()
+          );
+
+          /*  UPDATE students SET modified = (NOW())  */
+
+ +

You can pass parameters to the functions too:

+ + 
+          log(
+              squel.select()
+                  .from("students")
+                  .where("age IN ?", squel.str('RANGE(?, ?)', 1, 1.2))
+                  .toParam()
+          );
+
+          /*
+            {
+              text:  SELECT * FROM students WHERE (age IN (RANGE(?, ?))),
+              values: [ 1, 1.2 ]
+            }
+          */
+
+ + +
+ +
+

Automatic quotes

 + +

By default Squel does not add quotes around table names and field names. But you can tell it to do so using the + autoQuoteTableNames and autoQuoteFieldNames options:

+ + 
+        log(
+          squel.select({ autoQuoteTableNames: true, autoQuoteFieldNames: true })
+            .from("students", "s")
+            .field("s.name", "Student name")
+            .toString()
+        );
+
+        /*   SELECT `s`.`name` AS "Student name" FROM `students` `s`  */
+
+ +

Notice how squel was smart enough to detect the period separator within s.name when quoting. + You can turn off this behaviour if you wish:

+ + 
+        log(
+          squel.select({ autoQuoteTableNames: true, autoQuoteFieldNames: true })
+            .from("students", "s")
+            .field("s.name", "Student name", { ignorePeriodsForFieldNameQuotes: true })
+            .toString()
+        );
+
+        /*   SELECT `s.name` AS "Student name" FROM `students` `s`  */
+
+ +

You can also customize the quote character using the nameQuoteCharacter option:

+ + + 
+        log(
+          squel.select({ autoQuoteTableNames: true, autoQuoteFieldNames: true, nameQuoteCharacter: '|' })
+            .from("students")
+            .field("name", "Student name")
+            .toString()
+        );
+
+        /*   SELECT |name| AS "Student name" FROM |students|  */
+
+ +

As you can see above, Squel does however automatically add quotes to alias names. These too can be customized:

+ + 
+        log(
+          squel.select({ tableAliasQuoteCharacter: '|', fieldAliasQuoteCharacter: '~' })
+            .from("students", "s")
+            .field("name", "Student name")
+            .toString()
+        );
+
+        /*   SELECT name AS ~Student name~ FROM students |s|  */
+
+ +

And you can turn off automatic alias quoting if you so desire:

+ + 
+        log(
+          squel.select({ autoQuoteAliasNames: false })
+            .from("students", "s")
+            .field("name", "Student_name")
+            .toString()
+        );
+
+        /*   SELECT name AS Student_name FROM students s  */
+
+ +
+ +
+

Expressions

 + +

Squel lets you use use complex expressions strings in WHERE and ON clauses. For + example:

+ + 
+            log(
+                squel.select()
+                    .from("students")
+                    .where("(id < 500 AND (id > 100 OR name <> 'Thomas') AND "
+                            + "(age BETWEEN 20 AND 25 OR (name <> RANDOMNAME(?)))) OR (nickname = 'Hardy')", 10)
+                    .toString()
+            );
+            /*  SELECT * FROM students WHERE
+                    ((id < 500 AND (id > 100 OR name <> 'Thomas') AND (age BETWEEN 20 AND 25 OR (name <> RANDOMNAME(10))))
+                        OR (nickname = 'Hardy')) */
+
+ +

But having to change an expression string like that later on will be error-prone. It would be nice if you could build it + the same way you build queries. Luckily Squel provides an expression builder just for this purpose. To + get an instance of the builder:

+ + 
+            var q = squel.expr();
+
+ +

To build the above expression string these are the calls you would make:

+ + 
+            log(
+                squel.expr()
+                    .and("id < ?", 500)
+                    .and(
+                      squel.expr()
+                        .or("id > ?", 100)
+                        .or("name <> ?", 'Thomas')
+                    )
+                    .and(
+                      squel.expr()
+                        .or("age BETWEEN ? AND ?", 20, 25)
+                        .or("name <> ?", squel.str('RANDOMNAME(?)', 10))
+                    )
+                    .or("nickname = ?", 'Hardy')
+                    .toString()
+            );
+            /*  id < 500 AND (id > 100 OR name <> 'Thomas') AND (age BETWEEN 20 AND 25 OR name <> (RANDOMNAME(10)))
+                    OR nickname = 'Hardy'
+            */
+
+ +

Straight away the benefit of using the expression builder can be seen as it has simplified the + expression (AND has precendence over OR). Not to mention that it's easier to + figure out the meaning of the expression looking at this code than from the big string we were + using earlier.

+ +

As a convenience expression builder instances can be used in calls to where() and + join() when using the query builders:

+ + 
+            log(
+                squel.select()
+                    .field("s.id")
+                    .from("students", "s")
+                    .where(
+                        squel.expr()
+                            .and("s.name <> 'Fred'")
+                            .and(
+                              squel.expr()
+                                .or("s.id = 5")
+                                .or("s.id = 6")
+                            )
+                    )
+                    .join("teachers", "t",
+                        squel.expr()
+                            .and("s.id = t.sid")
+                            .and("t.name = 'Frances'")
+                    )
+                    .toString()
+            );
+            /*
+                SELECT s.id FROM students `s`
+                    INNER JOIN teachers `t` ON (s.id = t.sid AND t.name = 'Frances')
+                        WHERE (s.name <> 'Fred' AND (s.id = 5 OR s.id = 6))
+            */
+
+ +
+ +
+

Custom value types

 + +

Sometimes you might want to override how Squel formats certain types of values, e.g. Date instances. You could do the following:

+ + 
+            var myDate = new Date(2012, 4, 22),
+                myDate2 = new Date(2013, 5, 30);
+
+            log(
+                squel.update()
+                    .table("students")
+                    .set("start_date", myDate.getFullYear() + '-' + (myDate.getMonth()+1) + '-' + myDate.getDate())
+                    .set("end_date", myDate2.getFullYear() + '-' + (myDate2.getMonth()+1) + '-' + myDate2.getDate())
+                    .toString()
+            );
+            /*  UPDATE students SET start_date = '2012-5-22', end_date = '2013-6-30' */
+
+ +

Functional but no so elegant. A better approach is to register the Date object type + with Squel as a custom value type. We will need to supply a handler function which will get called whenever an + object of type Date is encountered:

+ + 
+            var myDate = new Date(2012, 4, 22),
+                myDate2 = new Date(2013, 5, 30);
+
+            /* Tell Squel how to handle Date objects */
+            squel.registerValueHandler(Date, function(date) {
+              return '"' + date.getFullYear() + '-' + (date.getMonth()+1) + '-' + date.getDate() + '"';
+            });
+
+            log(
+                squel.update()
+                    .table("students")
+                    .set("start_date", myDate)
+                    .set("end_date", myDate2)
+                    .toString()
+            );
+            /*  UPDATE students SET start_date = ("2012-5-22"), end_date = ("2013-6-30") */
+
+ +

We can register any type of object as a custom value type, not just Date. Squel checks to see if + the runtime type of a passed-in value matches one of the registered value types - meaning that sub-types are automatically + supported.

+ + 
+            /* OOP Inheritance mechanism (substitute your own favourite library for this!) */
+            Function.prototype.inheritsFrom = function( parentClassOrObject ) {
+              this.prototype = new parentClassOrObject;
+              this.prototype.constructor = this;
+              this.prototype.parent = parentClassOrObject.prototype;
+            };
+
+            /* Base type */
+            var ClassA = function() { this.a = 1; };
+
+            /* Sub-type */
+            var ClassB = function() { this.a = 2; };
+            ClassB.inheritsFrom(ClassA);
+
+            /* Register base type */
+            squel.registerValueHandler(ClassA, function(obj) {
+              return obj.a;
+            });
+
+            log(
+                squel.update()
+                    .table("students")
+                    .set("value", new ClassB())
+                    .toString()
+            );
+            /*  UPDATE students SET value = (2) */
+
+ +

We can even register handlers for primitive types such as strings and booleans. Simply pass in the + primitive type name as a string:

+ + 
+            squel.registerValueHandler('boolean', function(v) {
+              return v ? 'YES': 'NO';
+            });
+
+            log(
+                squel.update()
+                    .table("students")
+                    .set("value", true)
+                    .toString()
+            );
+            /*  UPDATE students SET value = (YES) */
+
+ +

We can even override the registered handler for a value type on a per-instance basis.

+ + 
+            /* Global handler */
+            squel.registerValueHandler(Date, function(date) {
+              return date.getFullYear();
+            });
+
+            log(
+              squel.update()
+                .registerValueHandler(Date, function(date) {
+                  return '"[' + date.getFullYear() + ']"';
+                })
+                .table('students')
+                .set('value', new Date(2013,5,1))
+                .toString()
+            );
+            /*  UPDATE students SET value = ("[2013]") */
+
+ +

Custom value types are processed correctly for parameterised queries:

+ + 
+            var myDate = new Date(2012, 4, 22),
+                myDate2 = new Date(2013, 5, 30);
+
+            /* Tell Squel how to handle Date objects */
+            squel.registerValueHandler(Date, function(date) {
+              return date.getFullYear() + '-' + (date.getMonth()+1) + '-' + date.getDate();
+            });
+
+            log(
+                squel.select()
+                    .from("students")
+                    .where("start_date >= ?", myDate)
+                    .where("end_date <= ?", myDate2)
+                    .toParam()
+            );
+
+            /*  
+            {
+              text:  SELECT * FROM students WHERE (start_date >= ?) AND (end_date <= ?),
+              values: [ '2012-5-22', '2013-6-30' ]
+            }
+            */                
+
+ +
+ +
+

Custom queries

 + +

You can customize Squel's query building mechanism quite easily. For instance, if you wanted to add + OFFSET clauses to UPDATE queries you could do it as such:

+ + 
+        /* We create a convenience method to make it easy to instantiate our customized UPDATE builder */
+        squel.myupdate = function(options) {
+          return squel.update(options, [
+            new squel.cls.StringBlock(options, 'UPDATE'),
+            new squel.cls.UpdateTableBlock(options),
+            new squel.cls.SetFieldBlock(options),
+            new squel.cls.WhereBlock(options),
+            new squel.cls.OrderByBlock(options),
+            new squel.cls.OffsetBlock(options),
+            new squel.cls.LimitBlock(options)
+          ]);
+        };
+
+        log(
+          squel.myupdate()
+            .table('students')
+            .set('status', 'active')
+            .limit(10)
+            .offset(2)
+            .toString()
+        );
+
+        /* UPDATE students SET status = 'active' OFFSET 2 LIMIT 10 */
+
+ +

Hopefully you can see that it is possible to totally override the built-in query building logic. Also notice + that each building block within a query can have a different set of options applied to it. + Check out squel.coffee to see + the available building blocks.

+ +

You can also build other types of queries and query clauses not already included in Squel. Let's say + you wanted to build a query structured as follows: PRAGMA {command} {param}:

+ + 
+        /* OOP Inheritance mechanism (substitute your own favourite library for this!) */
+        Function.prototype.inheritsFrom = function( parentClassOrObject ) {
+          this.prototype = new parentClassOrObject;
+          this.prototype.constructor = this;
+          this.prototype.parent = parentClassOrObject.prototype;
+        };
+
+
+        /* Create the 'command' clause */

+
+        /* 'PRAGMA FLUSH students' */

Cloning

 + +

You can create a copy of a query builder instance using its clone() method. For example:

+ + 
+          var select1 = squel.select().from('students');
+
+          var select2 = select1.clone().field('id').where('name = "david"');
+
+          log( select1.toString() );
+
+          /* SELECT * FROM students */
+
+          log( select2.toString() );
+
+          /* SELECT id FROM students WHERE (name = "david") */
+
+ +

Here is an example using an INSERT builder:

+ + 
+          var ins = squel.insert().into('students').set('name', 'David');
+
+          var insMathew = ins.clone().set('name', 'Mathew');
+
+          var insMark = insMathew.clone().set('name', 'Mark');
+
+          log( insMathew.toString() );
+
+          /* INSERT INTO students (name) VALUES('Mathew') */
+
+          log( insMark.toString() );
+
+          /* INSERT INTO students (name) VALUES('Mark') */
+
+ +
+ +
+

Database engines

 + +

Although you can use Squel's query customization mechanism to add support for your desired commands it would be + nice if Squel supported non-standard SQL commands for common database engines out of the box.

+

Well it actually does. Squel supports of the concept of SQL flavours, whereby a flavour is a non-standard + version of SQL which can be loaded and used at runtime. At the moment Squel provides support for the + Postgres, + MSSQL/Transact-SQL and MySQL flavours of SQL.

+ + Note: The API docs have more details on the specific features supported by each flavour. + +

Postgres

+ + The postgres flavor uses numbered query parameters by default. It also provides the RETURNING clause: + + 
+        squelPostgres = squel.useFlavour('postgres');
+
+        log(
+          squelPostgres.insert()
+            .into('table')
+            .set('field', 5)
+            .returning('*')
+            .toParam()
+        );
+
+        /*  
+            {
+                text: 'INSERT INTO table (field) VALUES ($1) RETURNING *'
+                values: [5]
+            }
+        */
+
+ +

MySQL

+ + The mysql flavour provides the ON DUPLICATE KEY UPDATE clause: + + 
+        squelMysql = squel.useFlavour('mysql');
+
+        log(
+          squelMysql.insert()
+            .into('table')
+            .setFields({
+                field1: 'abc',
+                field2: 3
+            })
+            .onDupUpdate('field1', 'upd')
+            .toParam()
+        );
+
+        /*  
+            {
+                text: 'INSERT INTO table (field1, field2) VALUES (?, ?) ON DUPLICATE KEY UPDATE field1 = ?'
+                values: ['abc', 3, 'upd']
+            }
+        */
+
+ +

MSSQL/Transact-SQL

+ +

Default date formatting:

+ + 
+        squelMssql = squel.useFlavour('mssql');
+
+        log(
+          squelMssql.insert()
+            .into('table')
+            .setFields({
+                field1: new Date('2012-12-12T04:30:00Z')
+            })
+            .toString()
+        );
+
+        /*  
+            INSERT INTO table (field1) VALUES(('2012-12-12 4:30:0'))
+        */
+
+ +

TOP:

+ + 
+        squelMysql = squel.useFlavour('mssql');
+
+        log(
+          squelMysql.select()
+            .from('table')
+            .field('field')
+            .top(10)
+            .toString()
+        );
+
+        /*  
+            SELECT TOP (10) field FROM table
+        */
+
+ +

OFFSET and FETCH NEXT:

+ + 
+        squelMysql = squel.useFlavour('mssql');
+
+        log(
+          squelMysql.select()
+            .from('table')
+            .field('field')
+            .limit(10)
+            .offset(5)
+            .toString()
+        );
+
+        /*  
+            SELECT field FROM table OFFSET 5 ROWS FETCH NEXT 10 ROWS ONLY
+        */
+
+ +

OUTPUT INSERTED:

+ + 
+        squelMssql = squel.useFlavour('mssql');
+
+        log(
+          squelMssql.update()
+            .table('table')
+            .output('id', 'blah')
+            .set('field', 1)
+            .toString()
+        );
+
+        /*  
+            UPDATE table SET field = 1 OUTPUT INSERTED.id AS blah
+        */
+
+ + 
+        squelMssql = squel.useFlavour('mssql');
+
+        log(
