Doctrine2 DQL where id in array

Question

I have a user and I want to check if it is in the qstn users relationship. I tried to execute the following DQL:

SELECT exmpl, qstn
    FROM Foo\BarBundle\Entity\Examples exmpl
    LEFT JOIN exmpl.question qstn
    LEFT JOIN qstn.users u
    WHERE :user IN (qstn.users)

But gave me the an error:

[Syntax Error] line 0, col 391: Error: Expected Literal, got 'qstn'

Is this even possible? If no, is there a work around (the doctrine way), not to nasty? (Not passing the users pre handed I could figure that out).

Answer 1

You just need one more join

SELECT exmpl, qstn
FROM Foo\BarBundle\Entity\Examples exmpl
LEFT JOIN exmpl.question qstn
LEFT JOIN qstn.users u
WHERE u.id = :userID

Answer 2

It appears you can use the DQL keyword "MEMBER OF" ex:

SELECT exmpl, qstn
   FROM Foo\BarBundle\Entity\Examples exmpl
   LEFT JOIN exmpl.question qstn
   LEFT JOIN qstn.users u
   WHERE :user MEMBER OF qstn.users

I hope this helps someone!
