Home -> Community -> Mailing Lists -> Oracle-L -> RE: Adhoc queries and limiting the amount of records queried...
many shops prohibit ad-hoc queries in busy OLTP databases and many of those
have datawarehouses where ad-hoc is allowed. IMHO that's the only way
prevent ad-hoc queries from causing problems in your OLTP environment.
SQL> select * form users where clue > 0;
no rows selected

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!!!
