I have a situation when user may create a query/filter criteria that will make SQL Select to select up to 200,000 records (or even more). The problem with this is that 1) it takes too much time and I don't know how to "allow" user to cancel the selection. 2) I really would prefer to "stop" or not allow user to select that many records. I wish there were a way to set some criteria in SQL Select that would stop selecting once the number of selected records has reached a certain number.

Any suggestion to deal with this situation?
