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.

The only thing you can do is make sure your query returns a row, and in the case where it currently doesn't return a row I have absolutely no idea what it would be that you would need to return. > > If it would be acceptable to always return some hard-wired dummy row in addition to the 0 or more rows that match the current query, then you could use a UNION to add the dummy row to the selection. 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. > > In your original post you referred to an application bug where a trigger does not run if the row count is 0.
