Yeah, my language is a little strong. I agree that quote is fine for a single use query, but I think that in the best case scenarios they tie and in worst cases placeholders fare dramatically better, so they should be in a programmer's arsenal. I also think that performing the N^M queries necessary to do this as a series of one-offs is unnecessary abuse of a database when 1 straight forward query will do.
In any case, TIMTOWTDI and best practice can mean ignoring Best Practice.
