如何将2个单独的临时表的输出合并到单个查询中？

Question

我正在使用SQL Server 2012并且有2个单独的T-SQL查询，尝试将它们合并为一个查询。

查询1：

   USE MyDatabase
   SELECT [Col A], [Col B], [Col C]
   INTO #TempTable
   FROM MyList
   WHERE [Date] >= '2018-01-01'

   SELECT * FROM #TempTable

   PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable

查询2：

   USE MyDatabase
   SELECT [Col A], [Col B], [Col C]
   INTO #TempTable2
   FROM MyList
   WHERE [StayDate] >= '2018-01-01'
   AND [DateCreated] <= '2018-01-27'

  SELECT * FROM #TempTable2

  PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable

我尝试使用UNION ALL语法，如下所示：

   USE MyDatabase
   SELECT [Col A], [Col B], [Col C]
   INTO #TempTable
   FROM MyList
   WHERE [StayDate] >= '2018-01-01'

   PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable


   UNION ALL

   SELECT [Col A], [Col B], [Col C]
   INTO #TempTable2
   FROM MyList
   WHERE [StayDate] >= '2018-01-01'
   AND [DateCreated] <= '2018-01-27'

   PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable

我的目标是将2个枢轴结果合并为一个输出表。 但是，这不起作用！ 如何重新编写此查询？

Answer 1

如果你想在这一个表，你将有只有一个into查询。 对于UNION ALL这是在第一个查询中：

   SELECT [Col A], [Col B], [Col C]
   INTO #TempTable
   FROM MyList
   WHERE [StayDate] >= '2018-01-01'

   PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable
   UNION ALL    
   SELECT [Col A], [Col B], [Col C]
   FROM MyList
   WHERE [StayDate] >= '2018-01-01'
   AND [DateCreated] <= '2018-01-27'

   PIVOT(SUM([Col B]) 
   FOR [Col A] IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable;

就是说，我认为您的查询无效。 此答案仅解决有关将数据保存到一个表的语法问题。
