Which is exactly what I described in my note to Steve (citing the same Data&Darwin source you used): that it is ANSI standard to use a subquery as one of the values in the set-clause, but that the syntax he showed with a FROM clause on the UPDATE as a whole is not standard ANSI syntax. Sorry if I'm seeming picky but I am in the middle of doing subqueries for SQL::Statement and I need to be picky about what is standard ANSI and what is a non-standard extension. I am by no means saying that the non-standard extension is somehow inferior or should be avoided, I'm just trying to pin down the difference. -- Jeff
