RE: Adhoc queries and limiting the amount of records queried...

Aside from severely restricting access to analysts who need to investigate problems in production data we limit the CPU time in their profile to 5 minutes. That's a pretty generous limit and they've never had any issues with it.

I just wanted to ping the list to see what other people have done to control or constrain adhoc query users???

We have a group that is struggling with the adhoc query piece that's in production. Some of the users end up firing off insane queries. The group is trying to find a way to limit the amount of records queried for, so that a wild query doesn't hose the database.

Appending a ROWNUM to the WHERE clause is one idea. Using USER PROFILEs is another. Any other thoughts??

Dare I ask...this custom app also runs on SQL Server, so SQL Server ideas would also be appreciated.

Many thanks!!!
