Hi,

I need to pivot the table. Rows for Name and columns for TestDate. If the percentage is null show NA and HasTest is not 1.
Show empty when percentage is null and HasTest is also null

DECLARE @Temp Table(ID INT, Name VARCHAR(50), Percentage INT, TestDate DATETIME, TestID INT, HasTest BIT)

INSERT INTO @Temp
SELECT '100','Ram','75','01/11/2011','85','1' UNION ALL
SELECT '100','Ram','100','01/11/2011','86','1' UNION ALL
SELECT '100','Ram','100','01/13/2011','87','1' UNION ALL
SELECT '100','Ram','50','01/13/2011','89','1' UNION ALL
SELECT '100','Ram','100','01/20/2011','90','1' UNION ALL
SELECT '100','Ram','100','01/21/2011','98','1' UNION ALL
SELECT '100','Ram','66','01/21/2011','99','1' UNION ALL
SELECT '100','Ram','100','01/21/2011','100','1' UNION ALL
SELECT '100','Ram','100','02/24/2011','128','1' UNION ALL
SELECT '100','Ram','100','02/24/2011','131','1' UNION ALL
SELECT '100','Ram','100','02/28/2011','138','1' UNION ALL
SELECT '100','Ram','66','03/07/2011','140','1' UNION ALL
SELECT '100','Ram','33','03/23/2011','151','1' UNION ALL
SELECT '100','Ram','100','03/25/2011','152','1' UNION ALL
SELECT '200','Siva','16','01/21/2011','95','1' UNION ALL
SELECT '200','Siva','100','01/21/2011','96','1' UNION ALL
SELECT '200','Siva','20','03/12/2011','150','1' UNION ALL
SELECT '200','Siva','100','04/01/2011','162','1' UNION ALL
SELECT '200','Siva','100','04/01/2011','164','1' UNION ALL
SELECT '200','Siva','100','4/1/2011','165','1'

SELECT * FROM @Temp

Thanks.

If you know the columns in advance, you could use the static PIVOT operator in SQL 2005, but I suspect you may not be able to do that given the nature of the data. In that case use dynamic pivoting. See here:
