SQL Server stored procedure error while executing from php

I am trying to execute a stored procedure from php.

In the php code iam sending a integer parameter to the stored procedure

$orderId =824;
$result =mssql_bind($sp, "@orderID", $orderId, SQLINT1, true, false);

I getting an error

mssql_execute() [function.mssql-execute]: messag开发者_如何学Ce: The formal parameter "@orderID" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output. (severity 16)

Can any one say the reason please

The document of mssql_bind gives the signature of it as:

bool mssql_bind  ( resource $stmt  , string $param_name  , mixed &$var  , int $type  [, bool $is_output = false  [, bool $is_null = false  [, int $maxlen = -1  ]]] )

So your problem is you're setting $is_output as true.

Use

$orderId =824;
$result =mssql_bind($sp, "@orderID", $orderId, SQLINT1, false, false);

You must create your stored procedure so that it indicates that the parameter as an OUTPUT variable.

DECLARE MyProc (@orderID int OUTPUT) AS ...
