Hi All
I'm using the sys.dm_exec_requests to check what's happening in my instance
There is a column called granted_query_memory, what does this column indicate? Does this indicate how many pages were brought from disk into memory to satisfy the query?
Thanks

Nothing to do with the buffer pool. That's the workspace memory grant for the query to do operations that themselves require memory. Hashes, sorts, exchanges, that sort of thing.
As I suggested a week or so ago (
http://www.sqlservercentral.com/Forums/Topic1365762-1550-1.aspx
), go look for Adam Machanic's workspace memory session videos. The one from PASS is online, so is the one he did at SQLBits

Thanks Gail
A question that might be out of the scope of this thread, are you aware of any upcoming SQL Server events in South Africa?
Thanks

I was wondering if there will be any SQLSaturdays\PASS Events happening on our side of the world anytime soon.
