mysql aux critères() dans symfony 1.4.9

Question

J'ai la requête complexe suivante dans mySQL

SELECT courseId,courseName 
FROM course WHERE courseId NOT IN (SELECT courseId FROM coursestaken NATURAL JOIN student WHERE grade >= 60 AND studentId =2) 
AND 
courseId NOT IN (SELECT courseId FROM stable WHERE studentId = 2) 
AND 
courseId NOT IN (SELECT DISTINCT courseId FROM prerequisites 
WHERE 
prereqId NOT IN (SELECT courseId FROM coursestaken NATURAL JOIN student WHERE grade >= 60 AND studentId =2 )) ; 

que quelqu'un peut me aider à convertir ce à une requête de critères() Propel?

Answer 1

Essayez d'utiliser la fonction de préparer Propel comme ci-dessous

$con=Propel::getConnection(); 
      $obj = $con->prepare("SELECT courseId,courseName 
FROM course WHERE courseId NOT IN (SELECT courseId FROM coursestaken NATURAL JOIN student WHERE grade >= 60 AND studentId =2) 
AND 
courseId NOT IN (SELECT courseId FROM stable WHERE studentId = 2) 
AND 
courseId NOT IN (SELECT DISTINCT courseId FROM prerequisites 
WHERE 
prereqId NOT IN (SELECT courseId FROM coursestaken NATURAL JOIN student WHERE grade >= 60 AND studentId =2 )) "); 
      $obj->execute(); 
      $resultset = $obj->fetchAll();
