Description:
------------
This is a simple bug that I can fix in the mssql query but I believe that this should be ignored automaticly by PHP. Basicly, I run this specific sql query and it outputs an Unknown Error. Then I go to query analyzer and the query works. But there's null values warnings. I can't use any @ to ignore the error, it doesn't *ignore* it. I can run any other queries in my php scripts and they work fine.

Reproduce code:

which works but I get this:

Warning: Null value is eliminated by an aggregate or other SET operation.

Expected result:
----------------
Sales    NAME    LineDate       Incoming   Outgoing   Area
12       David   Mar 21, 2005   16         13         QC
04       Rob     Mar 21, 2004   12         28         ON

Actual result:
--------------
PHP:
Query error!

Error message: DB Error: unknown error


MSSQL:
Query Outputs the good result.
but this in the warnings:

Warning: Null value is eliminated by an aggregate or other SET operation.
