Re: *****SPAM***** Re: if-clause to an exiting statement

I know it does not make sens "application bug" however consider the
following scenarion , looking at the Statement I sent I would like to
check if over the last 10 minutes a certain type of event was logged and
if NOT (row-count=0) then I would like to trigger and action.

hope it makes more sense.

Otherwise, perhaps the real problem is that you do not have a matching event in the database and the real solution is to add such an event.
