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

In my experience, I have sometimes seen a difference between :

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

and

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

The first statement is written on 3 lines, the second, on only one. I didn't believe it but THERE IS A DIFFERENCE !
