sql - 当 SQL Server 总计出现在第一行而不是表末尾时出错

Question

以下查询获取行和列总计。当我添加 ORDER BY 时，总列出现在第一行而不是底行。您建议的解决方案是什么？

Select
   isnull (Definition_, 'GrandTotal') AS 'Definition_',
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 1 THEN OrderQty END),0) AS January,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 2 THEN OrderQty END),0) AS Feburary, 
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 3 THEN OrderQty END),0) AS March,    
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 4 THEN OrderQty END),0) AS April,    
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 5 THEN OrderQty END),0) AS May,      
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 6 THEN OrderQty END),0) AS June,  
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 7 THEN OrderQty END),0) AS July,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 8 THEN OrderQty END),0) AS August,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 9 THEN OrderQty END),0) AS September,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 10 THEN OrderQty END),0) AS October,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 11 THEN OrderQty END),0) AS November,
   isnull (SUM(CASE DATEPART(MONTH,DueDate) WHEN 12 THEN OrderQty END),0) AS December,
   isnull (SUM(OrderQty),0) AS GrandTotal,
    
    FROM Production.WorkOrder
    GROUP BY GROUPING SETS((DATEPART(YEAR, DueDate), Definition_, ProductID),
    ())order by ProductID;

Answer 1

grouping如果该列是聚合的一部分，您可以使用which 返回 1 并且您可以通过以下方式在您的订单中使用它：

...
order by grouping(ProductID) 
        ,grouping(Definition_)
        ,grouping(DATEPART(YEAR, DueDate))
        ,ProductID;
