[freetds] Output parameters

I thought about that, but the stored procedure doesn't return any data,
and passing the result from mssql_execute to mssql_fetch_array throws an
error (invalid result id, the normal stuff).

This is the stored procedure:

CREATE PROCEDURE sp_web_WebsiteEnabled at WebsiteID INT, @Enabled TINYINT
                                  FROM WebsiteDivision wd (NOLOCK) 
                                  WHERE wd.Website_ID = @WebsiteID 
                                    AND wd.SalesordersAllowed = 1)
                 THEN 1
                 ELSE 0

Note that the same *does* work on another live server, but we haven't
yet figured out what the difference between the two servers is that
might cause output parameters to not get filled up.

Profiler shows a query where the result is returned correctly (SELECT
@P1, where @P1 represents @Enabled passed to the stored procedure).
Somehow the value from SELECT @P1 doesn't make it back to my PHP
variable $canLogin.

Kind regards,

Are you sure store does not return any output?? mssql return output
parameters after all data (rows, errors and so on) are sent. For
instance it can happen that a simple select or an insert return some
token that delays output parameters.
