This is a case where exceeding the spec would be a very good thing. And there has been lots of research on how to make more complex views updatable; see Date's _Introduction to Database Systems, 7th Edition_ for an in-depth discussion of this. That said, one step at a time is always good, and even having just the very simplest views updatable would be a very nice thing. cjs -- Curt Sampson <cjs@cynic.net> +81 90 7737 2974 http://www.netbsd.org Don't you know, in this new Dark Age, we're alllight. --XTC
