php - I need to put SQL native in query Builder Doctrine2

Question

i need to work with SQL NATIVE in query Builder doctrine 2 for using SQL Function (CONCAT,REPLACE,LDAP) . please Help me.

Answer 1

您可以尝试：

$connection = $this->get('doctrine')->getConnection();

$toto = "toto";
$foo = "foo";
$params = array('param1' => $toto, 'param2' => $foo);

$request = "SELECT * FROM table WHERE param1 = :param1 AND param2 = :param2";

try {
  $stmt = $connection->executeQuery($request, $params);
} catch (\PDOException $e) {
  // echo $e->getMessage();
}

while (($result = $stmt->fetch(\PDO::FETCH_ASSOC))) {
  // stuff with $result
}

如果您想对服务提出这样的请求，您可能需要：

use Doctrine\DBAL\Connection;

Answer 2

假设您有一个实体管理器存储在$this->em：

$dql = $this->em->createQuery('
    SELECT CONCAT(tbl.col1, ' ', tbl.col2), COALESCE(SUM(tbl.col3), 0)
    FROM myTable tbl
');

$result = $dql->getResult();

print_r($result);

这是针对 Doctrine 2 ORM 的。该表myTable可以通过包、类路径+类名或命名空间+类名（... FROM My\Namespace\Class\Model tbl ...）来寻址。
