在SQL Server 2008中，我有一个表tblStock 3列：行和列的平均动态枢纽
PartCode (NVARCHAR (50))
StockQty (INT)
Location (NVARCHAR(50))
下面一些示例数据：
我想要得到的以下输出，
我写了下面的查询来获取上面的输出，没有被正确返回Avg值：
IF OBJECT_ID('tempdb..#tblStock') IS NOT NULL /*Then it exists*/
DROP TABLE #tblStock
SELECT *
INTO #tblStock
FROM
(SELECT 'A' PartCode, 10 StockQty, 'WHs-A' Location
UNION ALL
SELECT 'B', 22, 'WHs-A'
UNION ALL
SELECT 'A', 1, 'WHs-B'
UNION ALL
SELECT 'C', 20, 'WHs-A'
UNION ALL
SELECT 'D', 39, 'WHs-F'
UNION ALL
SELECT 'E', 3, 'WHs-D'
UNION ALL
SELECT 'F', 7, 'WHs-A'
UNION ALL
SELECT 'A', 9, 'WHs-C'
UNION ALL
SELECT 'D', 2, 'WHs-A'
UNION ALL
SELECT 'F', 54, 'WHs-E') TAB
SELECT * FROM #tblStock
DECLARE @cols NVARCHAR (MAX)
SELECT @cols = COALESCE (@cols + ',[' + Location + ']', '[' + Location + ']')
FROM (SELECT DISTINCT Location FROM #tblStock) PV
ORDER BY Location
-- Since we need Total in last column, we append it at last
SELECT @cols += ',[AVG]'
-- Variable to replace NULL with zero
DECLARE @NulltoZeroCols NVARCHAR (MAX)
SELECT @NullToZeroCols = SUBSTRING((SELECT ',ISNULL(['+Location+'],0) AS ['+Location+']'
FROM (SELECT DISTINCT Location FROM #tblStock)TAB
ORDER BY Location FOR XML PATH('')),2,8000)
SELECT @NullToZeroCols += ',ISNULL([AVG],0) AS [AVG]'
DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT PartCode,' + @NulltoZeroCols + ' FROM
(
SELECT
ISNULL(CAST(PartCode AS VARCHAR(30)),''AVG'')PartCode,
AVG(StockQty) StockQty ,
ISNULL(Location,''AVG'')Location
FROM #tblStock
GROUP BY Location,PartCode
WITH CUBE
) x
PIVOT
(
AVG(StockQty)
FOR Location IN (' + @cols + ')
) p
ORDER BY CASE WHEN (PartCode=''AVG'') THEN 1 ELSE 0 END,PartCode'
EXEC SP_EXECUTESQL @query
任何人都可以知道这个问题该如何解决？
