Here I will explain how to convert row values to column values without using pivot in SQL Server.


In previous articles I explained Query to get duplicate records count, Query to remove duplicate records and many articles relating to SQL Server. Now I will explain how to write a query to convert row values to column values without pivot in SQL Server. In database I have one table UserInformation that contain data like as shown below

If you observe above table we have name “Suresh” which repeated for 3 times but it’s having different mobiles number in this case I want to display single username with all mobiles numbers like as shown below

To implement this kind of functionality we need to write the query like as shown below

DECLARE @tempUserInfo TABLE (UserName VARCHAR(50),Mobile VARCHAR(50))

INSERT INTO @tempUserInfo VALUES ('Suresh',9999999999)
INSERT INTO @tempUserInfo VALUES ('Suresh',8888888888)
INSERT INTO @tempUserInfo VALUES ('Suresh',7777777777)
INSERT INTO @tempUserInfo VALUES ('Mahesh',9000000000)
INSERT INTO @tempUserInfo VALUES ('Mahesh',9005000000)
INSERT INTO @tempUserInfo VALUES ('Madhav',8125000000)
INSERT INTO @tempUserInfo VALUES ('Madhav',8160000000)
INSERT INTO @tempUserInfo VALUES ('Madhav',8165555000)

;WITH UserDetails AS
FROM @tempUserInfo
,t1.Mobile AS website1,t2.Mobile AS website2,t3.Mobile AS website3
FROM @tempUserInfo t
LEFT OUTER JOIN UserDetails t1 ON t.UserName=t1.UserName AND t1.ColumnNumber=1
LEFT OUTER JOIN UserDetails t2 ON t.UserName=t2.UserName AND t2.ColumnNumber=2
LEFT OUTER JOIN UserDetails t3 ON t.UserName=t3.UserName AND t3.ColumnNumber=3 Order by t.userName desc
Above query will change row values to column values and the ouptput like as shown below

Hi Suresh, I stumbled upon ur post. i am looking for same logic. But my Sql query is within view. Hence i can't use insert to temp table to achieve this. Any alternative without using temp table ?

Thank U.

What if there are say, 15 rows, then we need to join 15 tables. So is there any alternative?
