将总计列添加到动态 SQL 数据透视表

如何解决将总计列添加到动态 SQL 数据透视表

有很多此类问题，但找不到与我要查找的内容相符的任何内容。

我正在使用另一篇文章中的代码，效果很好，但我想修改它以在表格底部添加一个总计行。

上一篇让创作者获得赞誉的帖子是：SQL Server dynamic pivot with multiple columns

我当前的表格如下：

工作组	平均	01/01/2021	01/01/2021	01/01/2021	等等...
蓝色	5	2	5	8
绿色	5	2	5	8

目标：

工作组	平均	01/01/2021	01/01/2021	01/01/2021	等等...
蓝色	5	2	5	8
绿色	5	2	5	8
总计	10	4	10	16

当前代码是：

DECLARE @colsEAST AS NVARCHAR(MAX);
DECLARE @pivotCountEAST AS NVARCHAR(MAX);
DECLARE @sqlEAST AS NVARCHAR(MAX);

SELECT @colsEAST = ISNULL(@colsEAST + ',','') + QUOTENAME(Load_Date)
FROM (SELECT disTINCT Load_Date FROM ##CE_tmpEast_ALL) AS Load_Date

SET @pivotCountEAST = N'SELECT Work_Group,' + @colsEAST +'
FROM (SELECT Work_Group,Load_Date,Count FROM ##CEtmp_East_ALL) AS Count
PIVOT(SUM(Count) FOR Load_Date IN (' + @colsEAST + ')) AS pvt';

SET @sqlEAST = '; WITH MTD_CountPivot AS (
'+@pivotCountEAST+'
),MTD_Pivot_Tables AS (
  SELECT Work_Group,AVG(Count) AS [AVG Count]
  FROM ##CEtmp_East_ALL
  GROUP BY Work_Group
)
SELECT MTD_CountPivot.Work_Group,MTD_Pivot_Tables.[AVG Count],' + @colsEAST + '
FROM
MTD_CountPivot

INNER JOIN MTD_Pivot_Tables ON MTD_CountPivot.Work_Group = MTD_Pivot_Tables.Work_Group';

EXEC sp_executesql @sqlEAST;

任何帮助将不胜感激！！！

谢谢

解决方法

您可以将 GROUPING SETS ((mcp.Work_Group),()) 添加到当前查询以获取小计。为此，需要创建另一个参数 @colsEAST2 以将生成的列标题日期列表保存为

SUM([2001-01-01]) AS [2001-01-01],SUM([2001-01-02]) AS [2001-01-02],SUM([2001-01-03]) AS [2001-01-03]

连同持有的 @colsEAST

[2001-01-01],[2001-01-02],[2001-01-03]

DECLARE @colsEAST       AS NVARCHAR(MAX);
DECLARE @colsEAST2      AS NVARCHAR(MAX);
DECLARE @pivotCountEAST AS NVARCHAR(MAX);
DECLARE @sqlEAST        AS NVARCHAR(MAX);

SELECT @colsEAST = ISNULL(@colsEAST + ',','') + QUOTENAME(Load_Date)
  FROM (SELECT DISTINCT Load_Date 
          FROM ##CE_tmpEast_ALL) AS Load_Date;    
SELECT @colsEAST2 = ISNULL(@colsEAST2 + ','') 
                + ' SUM('+QUOTENAME(Load_Date)+') AS '+QUOTENAME(Load_Date)
  FROM (SELECT DISTINCT Load_Date 
          FROM ##CE_tmpEast_ALL) AS Load_Date;    
SET @pivotCountEAST = N'SELECT Work_Group,' + @colsEAST2 +'
                          FROM (SELECT Work_Group,Load_Date,Count 
                                  FROM ##CE_tmpEast_ALL) AS Count
                         PIVOT(SUM(Count) FOR Load_Date IN (' + @colsEAST + ')) AS pvt
                         GROUP BY Work_Group';                             
SET @sqlEAST = '; WITH MTD_CountPivot AS (
'+@pivotCountEAST+'
),MTD_Pivot_Tables AS (
  SELECT Work_Group,AVG(Count) AS [AVG Count]
    FROM ##CE_tmpEast_ALL
   GROUP BY Work_Group
)
SELECT CASE WHEN GROUPING(mcp.Work_Group) = 0 
            THEN mcp.Work_Group 
            ELSE ''TOTAL'' 
             END AS Work_Group,SUM(mpt.[AVG Count]) AS Avg,' + @colsEAST2+ '
  FROM MTD_CountPivot mcp
  JOIN MTD_Pivot_Tables mpt 
    ON mcp.Work_Group = mpt.Work_Group
 GROUP BY GROUPING SETS ((mcp.Work_Group),())';    
EXEC sp_executesql @sqlEAST;
