在 MYSQL 存储过程上调用成员函数 fetchAll()

Question

I am trying to execute stored procedure, i want to have output as an associative array, but i am getting following error.

Call to a member function fetchAll() on boolean

and following is my PHP script which is calling the procedure

        $query_text = "CALL procedure1(?,?,@mobNum,@firstInsert);";
        $output=$this->pdo->prepare($query_text);
        $output=$output->execute(array($number,$code));
print_r($output->fetchAll(PDO::FETCH_ASSOC));

Answer 1

If your procedure1 has 4 parameters you should:

$query_text = "CALL procedure1(?,?, @mobNum, @firstInsert);";
$stmt = $this->pdo->prepare($query_text);
$stmt->bindParam(1,$number);
$stmt->bindParam(2,$code);
$result = $stmt->execute();
print_r($stmt->fetchAll(PDO::FETCH_ASSOC));

If just 2 change first line to $query_text = "CALL procedure1(?,?);"; then.

EDIT If you still ahve your error, try to handle sql error:

if ($result) {
    print_r($stmt->fetchAll(PDO::FETCH_ASSOC));
} else {
    echo "\nPDOStatement::errorInfo():\n";
    $arr = $stmt->errorInfo();
    print_r($arr);
}
