In particular, never put more into a single database transaction than is required for integrity; and there is no apparent reason why running a series of "SELECT 1" statements needs to be in a single transaction. (It's not blindingly obvious why you would want to do it in general, but I can imagine it possibly being useful for monitoring purposes.) -Kevin
