如何將2個單獨的臨時表的輸出合並到單個查詢中？

Question

我正在使用SQL Server 2012並且有2個單獨的T-SQL查詢，嘗試將它們合並為一個查詢。

查詢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

查詢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

我嘗試使用UNION ALL語法，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

我的目標是將2個樞軸結果合並為一個輸出表。 但是，這不起作用！ 如何重新編寫此查詢？

Answer 1

如果你想在這一個表，你將有只有一個into查詢。 對於UNION ALL這是在第一個查詢中：

   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;

就是說，我認為您的查詢無效。 此答案僅解決有關將數據保存到一個表的語法問題。
