php warning

Hi,

First I must say that i'm a database (MSSQL) programmer (not php
programmer) but I do a project with php part. This part is beeing done by
programmers in other firm, so I'm completely rookie in php.

The problem I have is a warning appearing when php executes one of my
stored procedures. Warning message:

"An output parameter variable was not provided"

I've searched google but I found nohing interesting about this. I checked
if procedures parameters declared in php are correct and they looks ok in
my opinion.

What can cause this warning?

Thanks
MP

It's not easy to say when not knowing how the code in this part of your script
looks like.

Looking at mssql_execute() user comments, there seems to be bit trouble with
the function.
http://se.php.net/manual/en/function.mssql-execute.php

--- user comment by SQL dot User ---
To receive output parameter from the procedure which returns one or several
recordsets, try this code:

....
mssql_bind($my_procedure, "@OutputParameter", SQLVARCHAR, true);
$result = mssql_execute($my_procedure);
while(mssql_next_recordset($result)) {
## do something
}

after listing last recordset output parameter will be available (strange...).

If you do not need output recordsets, just parameters, try this:

mssql_bind($my_procedure, "@OutputParameter", SQLVARCHAR, true);
$result = mssql_execute($my_procedure, true);

P.S. Tested on PHP 4.3.5.
