This library provides you MySQL functions for Doctrine2.

With composer

composer require mapado/mysql-doctrine-functions

Add the classes to your configuration

$config = new \Doctrine\ORM\Configuration();
$config->addCustomStringFunction('rand', \Mapado\MysqlDoctrineFunctions\DQL\MysqlRand::class);
$config->addCustomStringFunction('round', \Mapado\MysqlDoctrineFunctions\DQL\MysqlRound::class);
$config->addCustomStringFunction('date', \Mapado\MysqlDoctrineFunctions\DQL\MysqlDate::class);
$config->addCustomStringFunction('date_format', \Mapado\MysqlDoctrineFunctions\DQL\MysqlDateFormat::class);

$em = EntityManager::create($dbParams, $config);

You can of course pick just the functions you need.

Use with Symfony

If you install the library in a Symfony application, you can add this in your config.yml file (doctrine.yaml file if you use symfony flex)

# app/config/config.yml
doctrine:
    orm:
        # ...
        entity_managers:
            default:
                # ...
                dql:
                    numeric_functions:
                        rand:        'Mapado\MysqlDoctrineFunctions\DQL\MysqlRand'
                        round:       'Mapado\MysqlDoctrineFunctions\DQL\MysqlRound'
                    datetime_functions:
                        date:        'Mapado\MysqlDoctrineFunctions\DQL\MysqlDate'
                        date_format: 'Mapado\MysqlDoctrineFunctions\DQL\MysqlDateFormat'
                    # ... add all functions you need

Usage

You can now use the functions in your DQL Query

$query = 'SELECT RAND(), ROUND(123.45) 
        FROM ...
    ';
$em->createQuery($query);
