Jasny's Query builder for PHP

This library is designed to be the ultimate tool for building, splitting and modifying SQL queries.

Automatic smart quoting helps against SQL injection and problems with reserved keywords.

The query builder can be used standalone, in conjunction with Jasny's DB layer or in almost any framework.

The current version only support MySQL SQL queries

Installation

Jasny's Query builder is registred at packagist as jasny/dbquery and can be easily installed using composer. Alternatively you can simply download the .zip and copy the file from the 'src' folder.

Examples

An example to simple to be using a query builder

<?php
    use Jasny\DB\MySQL\Query;
    
    $query = Query::select()->columns('id, name')->from('foo')->where('active = 1');
    $result = $mysqli->query($query); // SELECT `id`, `name` FROM `foo` WHERE `active` = 1

Dynamicly apply paging and filtering on a query

<?php
    use Jasny\DB\MySQL\Query;
    
    $query = new Query("SELECT * FROM foo LEFT JOIN bar ON foo.bar_id = bar.id WHERE active = 1 LIMIT 25");
    if (isset($_GET['page'])) $query->page(3);

    $filter = isset($_POST['filter']) ? $_POST['filter'] : array(); // array('type' => 'bike', 'price between ? and ?' => array(10, 20))
    foreach ($filter as $field => $value) {
        $query->where($field, $value);
    }

    $result = $mysqli->query($query); // SELECT * FROM foo LEFT JOIN bar ON foo.bar_id = bar.id WHERE (active = 1) AND (`type` = "bike") AND (`price` between 10 and 20) LIMIT 25 OFFSET 50

Map fields for an INSERT INTO ... SELECT ... ON DUPLICATE KEY query

<?php
    use Jasny\DB\MySQL\Query;
    
    $columns = array(
        'ref' => 'ref',
        'man' => 'boy',
        'woman' => 'girl',
        'amount' => 'SUM(z.bucks)'
    );

    $select = Query::select()->columns($columns)->from('foo')->innerJoin('z', 'foo.id = z.foo_id')->groupBy('foo.id');
    $insert = Query::insert()->into('abc')->columns(array_keys($columns))->set($select)->onDuplicateKeyUpdate();

    $mysql->query($insert); // INSERT INTO `abc` (`ref`, `man`, `woman`, `amount`)
                            //  SELECT `ref` AS `ref`, `boy` AS `man`, `girl` AS `woman`, SUM(`z`.`bucks`) AS `amount` FROM `foo` LEFT JOIN `z` ON `foo`.`id` = `z`.`foo_id` GROUP BY `foo`.id`
                            //  ON DUPLICATE KEY UPDATE `ref` = VALUES(`ref`), `man` = VALUES(`man`), `woman` = VALUES(`woman`), `amount` = VALUES(`amount`)
