Persist - SQL Query

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

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

Supported SQL dialects

• Generic (ANSI standard)
• MySQL
• PostgreSQL (todo)
• SQLite (todo)

Installation

composer install jasny/persist-sql-query

Examples

Add WHERE conditions and an OFFSET to a SELECT query

use Jasny\Persist\SQL\Query;

$query = (new Query("SELECT * FROM foo LEFT JOIN bar ON foo.bar_id = bar.id WHERE active = 1 LIMIT 25"))
    ->where('type', 'bike')
    ->where('price between ? and ?', [10, 20])
    ->page(3);

echo $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

use Jasny\Persist\SQL\Query;

$columns = [
    'ref' => 'ref',
    'man' => 'boy',
    'woman' => 'girl',
    'amount' => 'SUM(z.bucks)'
];

$build = Query::build('mysql');

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

echo $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`)
