计算 SQL 服务器中动态列的按列总计

Question

我有以下输出，它是从以下存储过程生成的

   SET @sql = '

   SELECT  * FROM (SELECT [NAMES],logdate,[worked time] 
   from tmp_phys_table GROUP BY NAMES,LOGDATE,[WORKED TIME]) AS [SubTable] 
   PIVOT
   (
    MAX([worked time])
             FOR [logdate] IN ([' + @docDates + '])
       ) AS [Pivot] ;';

以上查询给出以下输出

现在我想按列进行总计，并在列的末尾包含一个名为总时间的新列，这些列是动态列，例如。可能有 3 列或 30 列。

Answer 1

应该是这样的：

   SET @sql = '

   SELECT *
   FROM (SELECT [NAMES], logdate, [worked time], [Total Time] 
         FROM tmp_phys_table 
         GROUP BY NAMES,LOGDATE,[WORKED TIME], [Total Time]
         ) AS [SubTable] 
   PIVOT
   (
    MAX([worked time])
             FOR [logdate] IN ([' + @docDates + '])
       ) AS [Pivot] ;';
