RE: Re[2]: Hotsos Symposium, Day 1

  This is exactly the reason I adopted the practice some time ago. I used to take them out when pasting the query into a package, etc. But, not so much anymore. With sufficient proof of performance degredation, I would take them out at once.

Thanks,

I have a colleague who uses WHERE 1 = 1 all the time. I asked him why some years ago.
It was because as he tuned or modified statements, he got tired of re-arranging the WHERE and AND clauses all the time. By starting off with WHERE 1 = 1, all the clauses that he would be re-arranging started with AND, so it saves him some bother.

Best reason I've heard so far.
