BTW: In SQL you have to use "field IS NULL", "field = NULL" returns NULL, so you're not any smarter than before :-)
That's because NULL is kinda like None, kinda like NaN, kinda like "we don't have any data here", and kinda like "we don't know what we should store here, so store NULL". It is, I think, the weirdest data value ever to be processed by any human or computer. Except that it's not a value at all. Other than when it is. ChrisA
