This is expected. =NULL will never work as NULL is not a value, it isn't
anything really. - and therefore it cannot be equal to anything.
You always have to use IS NULL.

Hey Will... I've experienced the same thing and would be curious to know
as well... I've just chalked it up to just being a pure syntax thing...
nothing more than that's just the way it is in SQL server... let's see

I'm guessing that it is just a syntax thing...somewhere in the SQL
Server engine, it makes it easier for them to handle the comparison.
Oddly, the update isn't like that...when you set a column to NULL, you
use col_name = NULL, not something like col_name TO BE NULL

Maybe if you SET the filed to the string 'NULL' but NULL has never been
tested by '=' that I've seen. It's not a value. I doubt an update
OK, I guess I stepped on a nerve here...and in retrospect, I should
have thought out my post more
-I should not have made a reference to SQL Server...the IS NULL
operator is part of the ANSI-92 standard, and would be used in any
