It's a little handier than seperate CREATE > TABLE and INSERT INTO statements, although it's sematically equivalent.

They are equivalent. btw, I assume that Tom used the term "abuse" in the supportive sense of the word? :) - Thomas -- Thomas Lockhart lockhart@alumni.caltech.edu South Pasadena, California
