T-SQL: select rows not equal to a value, including nulls

Question

How do I select rows which don\'t equal a value and also include nulls in the returned data? I\'ve tried:

SET ANSI_NULLS OFF
SELECT TOP 30 FROM Mails
WHERE a         


        

Answer 1

Try checking for NULL explicitly:

SELECT TOP 30 col1, col2, ..., coln
FROM Mails
WHERE (assignedByTeam <> 'team01' OR assignedByTeam IS NULL)
