SQL, Null value is eliminated by an aggregate or other SET operation.

Hi Experts,

The error message below showed up after I ran the query . I have checked the sub-query and there was no null value in there. I do not know if the warning message will affect the result or not? Thank you.

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

That's only a warning.
I understand that can be annoying especially if it appears in your application.
You can turn it off by executing the following command before the query:
SET ANSI_WARNINGS OFF

Chris Luttrell

PLEASE READ EVERYTHING ABOUT ANSI WARNINGS BEFORE CHANGING THAT SETTING!!!!!!!!
It is there and set to ON by default for a very good reason.

Vitor Montalvão

Where is saying that ON is the default value? By the MSDN article I posted above:
" The default value in the model database for SET ANSI_WARNINGS is OFF. If not specified, the setting of ANSI_WARNINGS applies. If SET ANSI_WARNINGS is OFF, SQL Server uses the value of the is_ansi_warnings_on column in the sys.databases catalog view."

Anyway, the OP can always set it back to ON after the SELECT statement.
SET ANSI_WARNINGS OFF

SELECT ...
(...)

SET ANSI_WARNINGS ON

Chris Luttrell

True, Vitor. And good example of how to do this for the one query and then turn it back on. I just see too many people think, "Oh, I should just always turn that off so it will never get in my way." But not think or realize the other effects of making that change.
