Using PIVOT and JOIN together
Consider This Query:
SELECT [Order Details].OrderID,
c.CategoryName,
COUNT(c.CategoryID)
FROM [Order Details]
INNER JOIN Products p
ON p.ProductID = [Order Details].ProductID
INNER JOIN Categories c
ON c.CategoryID = p.CategoryID
GROUP BY
[Order Details].OrderID,
c.CategoryName
ORDER BY
[Order Details].OrderID
this query returns this such result (Usnig Northwind Database):
I want to use Pivot with Join to get such this result:
OrderID Condiments Produce Seafood Condiments Grains/Cereals ...
--------------------------------------------------------------------------------------
10250 1 1 1 0 0 ...
10251 1 0 0 0 2 ...开发者_开发问答
...
How I can do this?
Thanks
WITH T
AS (SELECT [Order Details].OrderID,
c.CategoryName,
c.CategoryID
FROM [Order Details]
INNER JOIN Products p
ON p.ProductID = [Order Details].ProductID
INNER JOIN Categories c
ON c.CategoryID = p.CategoryID)
SELECT *
FROM T PIVOT ( COUNT (CategoryID) FOR CategoryName IN (
[Beverages],
[Condiments],
[Confections],
[Dairy Products],
[Grains/Cereals],
[Meat/Poultry],
[Produce],
[Seafood]) ) AS pvt
ORDER BY OrderID
