Ann,
My application lets users create filter/select criteria using any of 50+
conditions, some of which involve join criteria, some of which involve
extended date ranges (like years). I have absolutely no control on the
manner in which they may want to construct the filter criteria -- the
user gets to ask the questions.
I cannot allow for a query to run without end -- period. This is not
something that the client software should implicit have to care about.
Further, there is the problem with the client disconnect logic -- I saw
it just this week -- where I had a FB Server process run for over **200
hours** when there was no one/process connected to the database engine.
So the engine needs a 'governor' function (controllable, granted) --
period.
