Re: Nulls in database

You are trying to compare for a value that does not match, correct? Try this: SELECT [ID], [Project Name], [Start Construction Date], [Actual Completion Date] FROM common WHERE [Start Construction Date] <> '' OR [Actual Completion Date] <> '' Also, your query was saying if [Start Construction Date] is not equal to ' ' (space character). In SQL the not equal to comparison "!=" is actually "<>". -Toby ----- Original Message ----- From: "Richard" <richard@computech1.com> To: <php-windows@lists.php.net> Sent: Thursday, February 01, 2001 12:06 PM Subject: RE: [PHP-WIN] Nulls in database > I don't know ANYTHING about ANY of this stuff...but where I come from (C) > you would use 2 equal signs (==) to match values.
