我想从数据库中的表中获取计数,但它返回boolean!
$sql = "....";
$em = $this->getDoctrine()->getManager();
$stmt = $em->getConnection()->prepare($sql);
$stmt->execute();
$res = $stmt->fetchAll();
foreach ($res as $key => $value) {
$resultatRequete = "SELECT count(id) from inscriptions where seance_id =
'".$value['seance_id']."' and is_confirmed is not null";
$stmt2 = $em->getConnection()->prepare($resultatRequete);
$result_req = $stmt2->execute();
$res[$key]["count_inscrit"] = $result_req ;
}
return $res;
答案 0 :(得分:2)
execute方法返回一个布尔值以便成功/失败,然后你应该获取结果,例如:
// you can check on success ...
$success = $stmt2->execute();
$result_req = $stmt2->fetch();
$res[$key]["count_inscrit"] = $result_req ;
希望这个帮助
