Hi,
THis is example I found on msdn:
USE AdventureWorks ;
GO
SELECT DaysToManufacture, AVG(StandardCost) AS AverageCost
FROM Production.Product
GROUP BY DaysToManufacture;
-- Pivot query from the above
SELECT 'AverageCost' AS Cost_Sorted_By_Production_Days,
[0], [1], [2], [3], [4]
FROM
(SELECT DaysToManufacture, StandardCost
FROM Production.Product) AS SourceTable
PIVOT
(
AVG(StandardCost)
FOR DaysToManufacture IN ([0], [1], [2], [3], [4])
) AS PivotTable;
0 1 2 4
------- ------ --------- -------- -------
5.0885 223.88 359.1082 949.4105
Now the problem is when i try to use columns dynamically. I am getting each column heading twice.
The same thing happen in my real problem.
--dynamic
DECLARE @cols NVARCHAR(2000)
SELECT @cols = COALESCE(@cols + ',[' + convert(varchar(10),DaysToManufacture) + ']',
'[' + convert(varchar(10),DaysToManufacture) + ']')
FROM Production.Product
group by DaysToManufacture
--order BY DaysToManufacture
print @cols
DECLARE @query NVARCHAR(4000)
SET @query = N'SELECT *, '+
@cols +'
FROM
(SELECT DaysToManufacture, StandardCost
FROM Production.Product) AS SourceTable
PIVOT
(
AVG(StandardCost)
FOR DaysToManufacture IN ( '+
@cols +' )
) AS PivotTable';
EXECUTE(@query)
0 1 2 4 0 1 2 4
------- ------ --------- -------- ------- ------ -------- --------- ----------- --------
5.0885 223.88 359.1082 949.4105 5.0885 223.88 359.1082 949.4105
