No, it's not. That seems to be the standard way to win an argument around here. Declare the other person's comment orthogonal.
When a row is inserted, and there are no values supplied for one of the columns, one of three things can happen: the insert can fail; the inser can proceed, with a default value plugged in for the missing value, or a NULL can be placed in the location. Received on Sat Apr 24 2004 - 23:39:10 CEST
