Doctrine Querybuilder, binding Parameters - doctrine-orm

Question

My Select function of my QueryManager:
/**
* Führt eine SELECT - Query durch
*
* #param $select = array( array(column, [...]), table, shortcut )
* $orderby = array(column, sorting-type)
* $where = array( array( column, value, type[or, and] ), [...] )
* $innerjoin = array( table, shortcut, condition )
* $pagination = array( page, limit )
*
* #return array $data
*/
public function select($select,$orderby, $where, $innerjoin, $pagination)
{
$qb = $this->conn->createQueryBuilder()
->select($select[0])
->from($select[1], $select[2])
;
if ($orderby) {
$qb->orderBy($orderby);
}
if ($where) {
foreach($where as $cond) {
$x = 0;
if ( key($cond) == 0 ) {
$qb
->where($cond[0] . ' = ?')
->setParameter($x,$cond[1]);
}
elseif ( $cond[2] == 'and' ) {
$qb
->andWhere($cond[0] . ' = ?')
->setParameter($x,$cond[1]);
}
elseif ( $cond[2] == 'and' ) {
$qb
->orWhere($cond[0] . ' = :' . $x)
->setParameter($x,$cond[1]);
}
$x++;
}
}
if ($innerjoin) {
$qb->join($select[2],$innerjoin);
}
$this->sql = $qb->getSQL();
$this->totalRowCount = count( $qb->execute() ) ;
if ($pagination) {
$max = $pagination[0] * $pagination[1];
$first = $max - $limit;
$qb
->setFirstResult($first)
->setMaxResults($max)
;
}
$stmt = $qb->execute();
return $stmt->fetchAll();
}
I don't know why, but in action, this function produces a select query without inserted values for the parameters:
/**
* Lädt einen User nach dessen Username
*
* #param $username
* #return User $user | null
*/
public function getUser($username)
{
if($data = $this->select(array('*','users','u'), null, array( array('username',$username) ), null,null)) {
return $user = $this->hydrate($data);
}
return null;
}
I didn't get a result, and the query is not setup correctly:
array(0) { }
SELECT * FROM users u WHERE username = ?
In my opinion the Builder doesn't supstitute my parameters with the provided values ...
I got the latest version of Doctrine DBAL (2.4) and this version should support this features!
Thanks for Help and Suggestions :)

Answer 1

I also had this Problem. I have readed here doctrine 2 querybuilder with set parameters not working that:
You cant bind parameters to QueryBuilder, only to Query
But im creating SQL conditions as collected AND & OR experssions in deep nested objects, and the toppest object creates the query object. So i cant create the query object before, i always return expression objects.
So i solved the problem with direct including the variable into the prepared variable's position.
$qb->where($cond[0] . '=' . $cond[1]);
And because i expect strings there i added hard coded quotes. This is not the desired way, but at the moment i dont know how to solve that in an other way with binding parameters to the QueryBuilder object.
$expr = $d_qb->expr()->between($t_c, "'" . $date_from . "'", "'" . $date_from . "'");
Other suggestions?
Following codes results:
$expr = $d_qb->expr()->between($t_c, ':from', ':to');
$d_qb->setParameter('from', 1);
$d_qb->setParameter('to', 1);
or
$expr = $d_qb->expr()->between($t_c, ':from', ':to');
$d_qb->setParameter(':from', 1);
$d_qb->setParameter(':to', 1);
Results:
e0_.created BETWEEN ? AND ?
