How to use RLIKE with Doctrine 2?

Question

I'm using Doctrine 2 (Doctrine ORM 2.1, to be more precise) with MySQL and want to find entries, beginning with a number. With native SQL I would write something like:

SELECT * FROM table WHERE name RLIKE '^[0-9]';

But when I try to do it with DQL, I get the following error:

[Syntax Error] line 0, col 71: Error: Expected =, <, <=, <>, >, >=, !=, got 'RLIKE'
#0 .../Doctrine/ORM/Query/Parser.php(396): Doctrine/ORM/Query/QueryException::syntaxError('line 0, col 73:...')

#15 .../Doctrine/ORM/AbstractQuery.php(586): Doctrine/ORM/Query->_doExecute()
#16 .../Doctrine/ORM/AbstractQuery.php(392): Doctrine/ORM/AbstractQuery->execute(Array, 1)

What I tried was that:

$regex = '^[0-9]';
$em
    ->createQuery('
        SELECT t
        FROM MyEntity t
        WHERE t.visible = true 
            AND t.name RLIKE ?1
        ORDER BY t.name ASC')
    ->setParameter(1, $regex)
    ->getResult();

and that:

$regex = '^[0-9]';
$em
    ->createQueryBuilder()
    ->select('t')
    ->from('MyEntity', 't')
    ->where('t.visible = true')
    ->andWhere(new Doctrine\ORM\Query\Expr\Comparison('t.name', 'RLIKE', '?1'))
    ->orderBy('t.name', 'ASC')
    ->getQuery()
    ->setParameter(1, $regex)
    ->getResult();

Do you have any idea, how I could use RLIKE in DQL?

Best regards ;)

Good question, unfortunately I don't have a good answer.

The only thing that comes to mind is to create your own DQL function, like mentioned in the documentation. Good luck with that ;)

Also look at this question, maybe it will help.

If you solve this problem, please post an answer.
