How to add operators in doctrine2 query builder where statement

Question

Im trying to select from a table where the selected duration divided by the entry duration equals has no remainder.

$qb = $em->createQueryBuilder()
->from('AcmeBlogBundle:Entry', 'e')
->andWhere(":duration % e.duration = 0")
->setParameter('duration', $duration);

This returns the error:

[Syntax Error] line 0, col 226: Error: Expected =, <, <=, <>, >, >=, !=, got '%' 

This would work in plain SQL. Does anybody know how to do this with Doctrine's query builder?

Answer 1

The symbol % is not a DQL operator. Try this:

$qb = $em->createQueryBuilder()
->from('AcmeBlogBundle:Entry', 'e')
->andWhere("mod(:duration,e.duration) = 0")
->setParameter('duration', $duration);

Or read this: http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/dql-doctrine-query-language.html The 12.5.1 paragraph.

MOD(a, b) - Return a MOD b.
