I don't find any derivation in the standard that would permit this. The only thing I could find are variations on SET (a) = x -- no parentheses SET (a, b) = (x, y) SET (a, b) = ROW (x, y) where x and y are some sort of value expression. I would have expected the sort of thing that you describe, but if you know how to derive that, I'd like to see it. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
