Hi folks . . . hopefully this is just a quick question.
Was just reading BOL regarding the OUTPUT clause. I'd like to take a column value generated from an INSERT and pass it to a variable.
Does the variable have to be a TABLE variable, or is there a way to pass it into a common variable such as INT or NVARCHAR (or, in my particular situation, a UNIQUEIDENTIFIER)?
Thanks!

You can either use a table (table variable, temporary table, permanent table) (results to into it), or not (results to client). But not to a "regular" variable. See the BOL OUTPUT Clause entry.

Okay, that's what I figured.

I ended up just creating a simple SELECT statement for the column immediately following the INSERT. I'm just writing a quick 'n dirty, and it's insignificant enough that having to create a TABLE variable for it would be unnecessary overkill.

Thanks!

Say what? Overkill???

DECLARE @test-2 TABLE (Col1 uniqueidentifier);

INSERT INTO .....

OUTPUT i.MyUniqueIdentifierColumn INTO @test-2

....

SELECT * FROM @test-2;

Edit: my original reply was a bit too flippant -- didn't want anyone to take it the wrong way!

Maybe "overkill" wasn't the right word -- rather, what I was doing wasn't terribly big, and I didn't think it necessitated the need to create a table variable.
