I have a view that I am building that uses left outer joins to combine multiple views and tables. Up to a point of adding addition (needed) views and tables to this join it will execute in about 1:40 sec, and returns about 850 rows, but if I add just one more table/view then the execution time goes to over 30 minutes and still running. I have tried replacing/substituting different tables/views in the join, but nothing seems to help. Does anyone have any idea of what could possibly be happening to me?
