#13 Getting errors in stored procedure using php sqlserver-2008

[Manish Sonwal]

Hello guys,
I am working with ADODB php and sql server 2008. I want to execute a stored procedure using this code.

$login = $db->PrepareSP("adodb.LocFillData();");
$db->InParameter($login,$user_name,$password);

When i do this, i am getting some error messages, and code is not running.

Can you please help me in writing correct stored procedure execution code for sql server 2008 using php.
And please tell me where does stored procedures are defined in sql server 2008.
Any help would be greatly appreciated.

Thanks
