There is no Boolean data type in SQL Server. One that is often used instead of Boolean is the Bit data type. It can store the values 0, 1 and NULL.
CREATE TABLE #MyTable(
Id INT NOT NULL,
TrueBoolean BIT NOT NULL DEFAULT 1,
FalseBoolean BIT NOT NULL DEFAULT 0,
INSERT INTO #MyTable(Id) VALUES
SELECT * from #MyTable
--1 1 0 NULL
SET TrueBoolean = 0
WHERE UndefBoolean IS NULL
--1 0 0 NULL
SELECT * FROM #MyTable
WHERE FalseBoolean = 1
-- empty result set

Grabel's Law: 2 is not equal to 3 -- not even for very large values of 2. Pat Phelan's Law: 2 very definitely CAN equal 3 -- in at least two programming languages
