I probably should be able to figure this out on my own, but if I'm barking up the wrong tree, I don't want to spend the time, and searching hasn't helped.
I want to update a row in the table using the result of a subselect as a value in one round trip. In DBI, I would do this: prepare( 'update make_model_years set performancerating=(select sum(perf)/count(*) from ratings where year=? and makeid=? and modelid=?) where year=? and makeid=? and modelid=?' ); execute( 1973, 12, 185, 1973, 12, 185 ); I haven't seen anything that indicates I can use a subselect in the set clause of RDBOM->update_table. Thanks for any hints, Fred ____________________________________________________________________________________ Food fight? Enjoy some healthy debate in the Yahoo!
