SQL Server 2014 数据透视表行和列月授权总计

Question

如何在下表中添加行和列总计？ 我想按月计算总计和总计。

但是，我做不到。

    SELECT *
FROM(
  SELECT
    YEAR(DueDate) [Year],
    CASE MONTH(DueDate)
      WHEN 1 THEN 'January'
      WHEN 2 THEN 'February'
      WHEN 3 THEN 'March'
      WHEN 4 THEN 'April'
      WHEN 5 THEN 'May'
      WHEN 6 THEN 'June'
      WHEN 7 THEN 'July'
      WHEN 8 THEN 'August'
      WHEN 9 THEN 'September'
      WHEN 10 THEN 'October'
      WHEN 11 THEN 'November'
      WHEN 12 THEN 'December'
    END as [Month],
    ProductID,
    OrderQty
  FROM Production.WorkOrder
) WorkOrders
PIVOT
(
  SUM(OrderQty)
  FOR [Month] IN (
    [January],[February],[March],[April],
    [May],[June],[July],[August],
    [September],[October],[November],[December]
  )
) AS PivotTable
ORDER BY [Year], ProductID

Answer 1

使用条件聚合比限制性的PIVOT 运算符更容易。

没有样本数据，也没有预期的结果，这没有经过测试，但您应该能够通过以下方式实现您所追求的目标：

SELECT CASE WHEN GROUPING(DATEPART(YEAR,DueDate)) = 0 THEN
         CAST(DATEPART(YEAR,DueDate) AS varchar(50))
       ELSE 'GrandTotal' END AS [Year],
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 1 THEN OrderQty END) AS January,  --Don't use single quotes for alaises,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 2 THEN OrderQty END) AS Feburary, --it can be very confusing to read.
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 3 THEN OrderQty END) AS March,    --Single quotes are for literal strings.
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 4 THEN OrderQty END) AS April,    --Using ' for alias only work in the SELECT too,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 5 THEN OrderQty END) AS May,      --something like ORDER BY 'January' would not
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 6 THEN OrderQty END) AS June,     --order by data by the column aliases as 'January'.
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 7 THEN OrderQty END) AS July,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 8 THEN OrderQty END) AS August,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 9 THEN OrderQty END) AS September,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 10 THEN OrderQty END) AS October,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 11 THEN OrderQty END) AS November,
       SUM(CASE DATEPART(MONTH,DueDate) WHEN 12 THEN OrderQty END) AS December,
       SUM(OrderQty) AS GrandTotal,
       ProductID
FROM Production.WorkOrder
GROUP BY GROUPING SETS(
    (DATEPART(YEAR, DueDate), ProductID),
    (DATEPART(YEAR, DueDate)),
    ()
);
