I got it right but this is a really bad question for people who are still stuck with SQL Server 2000. These types of questions should probably identify the version of SQL Server the question is for.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I also found the wording of the question a bit dubious. How should I know what somebody tries to achieve. It wouldn't be the first time that someone executes a command, trying to achieve something but actually achieving something totally different.

This seemed easy to me, for once. I thought I knew the answer, but just to be sure I googled "DBCC FREESESSIONCACHE".

The very first item returned confirmed the answer:

"DBCC FREESESSIONCACHE (Transact-SQL)

Flushes the distributed query connection cache used by distributed queries against an instance of Microsoft SQL Server.

msdn.microsoft.com/en-us/library/ms187781.aspx - 19k - Cached - Similar pages - Note this"

I also googled 'DBCC FREESESSIONCACHE' to find the answer. I agree version should be given.

Maybe we should post the answer and try to guess the correct question 😉

Only kidding really 😀

Most QOD now are 2005 and 2008 related anyway 😛

When I do not see the version specified I become suspicious but then maybe that's just the cynic in me :w00t:

Far away is close at hand in the images of elsewhere.

"DBCC FREESESSIONCACHE (Transact-SQL)

Please if you can explain that which buffers/caches are flushed in this case, specifically if comparing with DBCC DROPCLEANBUFFERS (data buffers)?

Thank you![/font]
