Boolean Operations Between Bit Variables in SQL

Use Bitwise Operators in T-SQL to do AND/OR/XOR (&/|/^) between two or more bit/integer variables.

You can use z = x and y in VB where x,y,z is Boolean, in T-SQL:

SET @z =
@x & @y
Or swap two Integer variables:

DECLARE @X int, @y int

SET @x = 5
SET @y = 6

SELECT @x as X, @y as Y

SET @x = @x ^ @y
SET @y = @y ^ @x
SET @x = @x ^ @y

SELECT @x as X, @y as Y
