I have the following query builder:
$queryBuilder = $this
->createQueryBuilder(\'recipient\')
->leftJoin(\'recipient.message\', \'message\')
-&
There is a bug reported in #4846 and it seems to be related to #sqlmode_only_full_group_by and there are some examples abaut what does it mean here. Until a proper fix comes out a solution would be to add ->addSelect('message')
to the query (I don't know if it fixes the issue or doctrine rewrites the query anyway), but that way doctrine will hydrate massages as well which maybe not desired or disable ONLY_FULL_GROUP_BY sql mode, but then, mysql maybe can return invalid data.
