Because my company reuire we use 0.4.1 version, the version don't support IN clause. I want to use the OR clause(example:where id=1 or id=2 or id=3) to implement the IN clause(example: id in(1,2,3) ). I know it will be slower especially when the list after "in" is very long. Could anybody can tell me why is slow when use OR clause to implement In clause?
Thanks, LiuLei
