How to Swap the values of two columns in SQL Server

How to Swap the values of two columns in SQL Server
Suppose you have a Customer table in the database with the following data and you want to interchange the values of columns Name and Address.


SELECT * FROM CUSTOMER


Just write a simple update query for Address table like as :

UPDATE Customer SET Name=Address , Address=Name

Now After query execution you will find the the values of columns Name and Address have been interchanged.
Note : If column is identity ,then swapping is not possible.

SELECT * FROM CUSTOMER
