    I understand all this but why doesn't Microsoft make everyones life easier and make it work as everyone expects

    i.e. NULL does equal NULL

    So we can use col2 = NULL or col2 != null instead of IS NULL or IS NOT NULL.

    It would lead to so many less bugs

    Apart from the issue of following ANSI SQL standards, when I add a clause "WHERE col1=col2" I want to be sure that the two columns contain identical data, not just that they both happen to have been left blank, or generated by a non-matched item in an outer join.
