When I use the WHERE clause my basic entity values are NULL

Question

I want to refac a native SQL query with the doctrine querybuilder. In this case I get the following error: The query executes and returns a result (with and without joins). But when I add a simple WHERE the basic entity values are NULL.

Tested
- QueryBuilder (complex: as default I need six joins)
- QueryBuilder (simple: no join)
- HQL
- different getResult() and execute() calls

Some code

The basic values are filled (like id and title).

$qb = $this->createQueryBuilder('artikel')
           ;
return $qb->getQuery()->execute();

The basic values are null except the id.

$qb = $this->createQueryBuilder('artikel')
           ->andWhere('artikel.id = :ids')
           ->setParameter('ids', '1010729320')
           ;
return $qb->getQuery()->execute();

Why are the basic value null when I use the WHERE clause?

Answer 1

It's very easy. ;)

Problem was

The datatype of the id is an integer and the given param has type string.
So it differs and php does no auto-cast something.

Solution

Remove the ' before and after the id.

The correct code

Note: spot the missing '

$qb = $this->createQueryBuilder('artikel')
           ->andWhere('artikel.id = :ids')
           ->setParameter('ids', 1010729320)
           ;
return $qb->getQuery()->execute();

For me the problem occures before, but this is an other story (I write some cents in the comment above).

Thank you all
