Try using sybase_fetch_row, but have to refer to the fields by numeric cell references.

We figured this out...

Basically the $db was already called earlier in the code... So here's how to make the code work right...

$connection = @sybase_connect("server_name", "user", "pass") 
	or die("Couldn't connect to the server");

$db = @sybase_select_db("db_name", $connection) 
	or die("Couldn't select database.");

// here's the change take out the $db so it look like

$query = sybase_query("EXEC ops_select_mfr @mf_id=$mf_idx");

In Sybase once you connect to the database you can keep on truckin with out calling it again... not sure that it was meant to be this way, but it works...

It works as expected:

This function only 'binds' the connection to a database. So you should be using the $connection variable instead as 
it holds the actual link resource.
