Hello all,

When i use the DQL operator "new" to build data transfert object with string literal expression as field in object constructor, the call to Query::getResult thrown an exception.

Condition :
The string literal expression must be the first parameter of the constructor.

Following DQL :

$query = $em->createQuery('SELECT NEW CustomerDTO('some scalar string', c.name, c.email) FROM Customer c');

$users = $query->getResult();

Thrown exception :
{quote}
ContextErrorException: Notice: Undefined variable: fieldType in doctrine/orm/lib/Doctrine/ORM/Query/SqlWalker.php line 1527
{quote}

That happens because in SqlWalker::walkNewObject on the AST\Literal switch case. There is no case for AST\Literal::STRING, so $fieldType isn't defined.

I have also noted if the scalar string isn't the first parameter, $fieldType take the type of previous foreach element.
