Expression mysql NOW() in Doctrine QueryBuilder

问题:

How to use the expression mysql NOW() in doctrine querybuilder?

回答1:

In Doctrine2 you have to use one of the following instead of NOW().
This:

CURRENT_TIMESTAMP()

Or:

...
createQuery(...'WHERE x.date = :now')
->setParameter('now', new \DateTime('now'))
...

If you want only time or only date use one of those: CURRENT_TIME() and CURRENT_DATE()

Documentation can be found here.

回答2:

Using query builder it would look like this:

$qb
    ->select('B')
    ->from('RandomBundle:Banana', 'B')
    ->where(
        $qb->expr()->gt('B.expiresAt', ':now')
    )
    ->setParameter('now', '\'CURRENT_TIMESTAMP()\'');

Note: extra quotes on parameter set is required to get CURRENT_TIMESTAMP() function working.

Or simply

$qb
    ->select('B')
    ->from('RandomBundle:Banana', 'B')
    ->where(
        $qb->expr()->gt('B.expiresAt', 'CURRENT_TIMESTAMP()')
    );
