Boolean 'NOT' in T-SQL not working on 'bit' datatype?

Question

Trying to perform a single boolean NOT operation, it appears that under MS SQL Server 2005, the following block does not work

DECLARE @MyBoolean bit;
SET @My         


        

Answer 1

Your solution is a good one... you can also use this syntax to toggle a bit in SQL...

DECLARE @MyBoolean bit;
SET @MyBoolean = 0;
SET @MyBoolean = @MyBoolean ^ 1; 
SELECT @MyBoolean;
