If you're not doing hundreds of thousands of identical ones at a time,
it's still very much a good idea. The costs of parsing and transmission
are usually pretty insignificant, and the readability/maintenance
benefits are huge.
It's only when dealing with bulk loading that this sort of thing starts
to be worth thinking about.
Thanks for the clarification.
I'm till a bit surprised that parsing the statement _with_ a column list is mesurably slower than withou a column list.
