Php 执行PDO存储过程时出错

执行下面的代码时，我在下面得到一个错误

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: 
[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '@P1'.' in 
E:\xampp\htdocs\kbs\inc\settings_inc.php:62 Stack trace: #0

E:\xampp\htdocs\kbs\settings.php(186): include('E:\xampp\htdocs...') #2 {main} thrown in 
E:\xampp\htdocs\kbs\inc\settings_inc.php on line 62

我们将不胜感激

//PHP代码

$clientID=0;
$isEdit=0;
$stmt = $conn->prepare("EXECUTE sp_AddEditCustomers(?,?,?,?,?,?,?,?,?,?,?)");
$stmt->bindParam(1, $clientID, PDO::PARAM_INT); 
$stmt->bindParam(2, $_POST[FName], PDO::PARAM_STR, 15);
$stmt->bindParam(3, $_POST[MName], PDO::PARAM_STR, 15);
$stmt->bindParam(4, $_POST[LName], PDO::PARAM_STR, 15);
$stmt->bindParam(5, $_POST[CAddress], PDO::PARAM_STR, 50);

$stmt->execute();

下面是来自探查器的输出。在这里它得到了错误的语法错误。我在执行时也会遇到同样的错误

此存储过程中没有

@P1

？@P1是在执行期间由sql server准备的语句生成的。我已通过探查器进行了跟踪，这是传递给sql server的内容。
