Comound Operators SQL Server 2008

SQL 2008 now supports compound operators, which is available in other databases since long time

x += 2
is equivalent to x = x+2



Below are the compound operators which are supported by sql server
+=
-=
*=
/=
%=
&=
^=
|=

We can also assign values while declaring variable.
DECLARE @x INT
SET @x = 135

which can be rewritten as
DECLARE @x1 INT = 135



lets see an example

DECLARE @x1 INT
SET @x1 = 135
SET @x1 = @x1 + 2
SELECT @x1

which can be rewritten as

DECLARE @x1 int = 135;
SET @x1 += 2
SELECT @x1
