Complex WHERE clauses using the PHP Doctrine ORM

Question

I\'m using the PHP Doctrine ORM to build my queries. However, I can\'t quite seem to figure how to write the following WHERE clause using DQL (Doctrine Query Language):

Answer 1

$q->andWhere("category1 IN ( $subcategory_in_clause )
              OR category2 IN ( $subcategory_in_clause )
              OR category3 IN ( $subcategory_in_clause )");

would you be so kind to try this variant, not sure if it works, but worth a shot
