you are really starting to annoy me. you have asked so many very basic questions, it makes me wonder if you are just a troll. If you really do not understand what the heck you are doing, you might want to find another line of work or go to school.

You achieve this by breaking you query down into parts, testing and more testing. you have too many sub-selects which is another indication you are clueless. Get a good book on SQL, start up an Oracle database and start testing. Received on Thu Apr 16 2009 - 09:26:48 CDT
