Sql 如何修改现有查询以考虑自定义表中的特定列？,sql,sql-server,join,left-join,Sql,Sql Server,Join,Left Join,我正在使用SQL Server 2014和当前查询的摘录，如下所示。我的问题与我查询的最后一条SELECT语句有关。现在它工作正常，输出如下： ReservationStayID ........... XBEV01 XBEV02 XBEV03 XFOOD1 XFOOD2 215 ........... 1500 0 0 300 100 356 ........... 500

我正在使用SQL Server 2014和当前查询的摘录，如下所示。我的问题与我查询的最后一条SELECT语句有关。现在它工作正常，输出如下：

ReservationStayID ........... XBEV01   XBEV02   XBEV03  XFOOD1   XFOOD2
     215          ...........  1500      0        0      300       100
     356          ...........   500      200      0      600       700
     620          ...........   300      0        600     0        200

现在我创建了一个名为Extras的表，它如下所示：

 Code       Description          RevenueType
XBEV01     Beverage Bar A      Beverage Charge
XBEV01     Beverage Bar A      Beverage Charge
XBEV01     Beverage Bar A      Beverage Charge
XFOOD1     Food A              Food Charge
XFOOD2     Food B              Food Charge

ReservationStayID ........... Beverage Charge     Food Charge
     215          ...........  1500                  400
     356          ...........   700                 1300
     620          ...........   900                  200

我想修改我的查询，以便输出如下所示：

 Code       Description          RevenueType
XBEV01     Beverage Bar A      Beverage Charge
XBEV01     Beverage Bar A      Beverage Charge
XBEV01     Beverage Bar A      Beverage Charge
XFOOD1     Food A              Food Charge
XFOOD2     Food B              Food Charge

ReservationStayID ........... Beverage Charge     Food Charge
     215          ...........  1500                  400
     356          ...........   700                 1300
     620          ...........   900                  200

我知道我需要与Extras表的Code列和P5FolioCharge表的FOC_TRANSACTIONCODE列进行左连接，但我不知道如何在查询中实现它。我想我需要修改查询的最后一个SELECT语句中的SUM语句

以下是我当前查询的摘录：

USE MyDatabase

    FROM ReservationStayDate
   GROUP BY ReservationStayID, datename(m,StayDate) + ' ' +  cast(datepart(yyyy,StayDate) as varchar)

  LEFT JOIN

         datename(m,FOC_DATE) + ' ' + cast(datepart(yyyy,FOC_DATE) as varchar) as [FOCMTH], 

        SUM(case FOC_TRANSACTIONCODE when 'XBEV01' then foc_netamount else 0 end) as 'NetAmount(XBEV01)',
        SUM(case FOC_TRANSACTIONCODE when 'XBEV02' then foc_netamount else 0 end) as 'NetAmount(XBEV02)',

 FROM P5FOLIOCHARGE

 GROUP BY FOC_ACCOUNT, datename(m,FOC_DATE) + ' ' + cast(datepart(yyyy,FOC_DATE) as varchar)

) y ON y.FOC_ACCOUNT = j.FOH_ACCOUNT

更新：下面是我的Pivot查询，它基于建议的解决方案，非常有用，并且可以正常工作。我创建了一个视图表HOLDINGS3，并进行了一个透视查询以进入视图：

    (SELECT ReservationStayID,
            PropertyCode,
            [Beverage Charge],
            [Food Charge]

    FROM (SELECT 
          ReservationStayID,
          PropertyCode,
          RevenueType,
          FOC_NETAMOUNT

      FROM HOLDINGS3

    )ab

      PIVOT (SUM(foc_netamount)

      FOR RevenueType IN ([Beverage Charge], [Food Charge]
         )) as pvt)

我们开始吧。您的查询很长，所以这可能不起作用，但希望它能给您一个想法。本节阻碍了您：

SELECT 
         FOC_ACCOUNT,
         datename(m,FOC_DATE) + ' ' + cast(datepart(yyyy,FOC_DATE) as varchar) as [FOCMTH], 

        SUM(case FOC_TRANSACTIONCODE when 'XBEV01' then foc_netamount else 0 end) as 'NetAmount(XBEV01)',
        SUM(case FOC_TRANSACTIONCODE when 'XBEV02' then foc_netamount else 0 end) as 'NetAmount(XBEV02)',
        SUM(case FOC_TRANSACTIONCODE when 'XBEV03' then foc_netamount else 0 end) as 'NetAmount(XBEV03)'
        SUM(case FOC_TRANSACTIONCODE when 'XFOOD1' then foc_netamount else 0 end) as 'NetAmount(XFOOD1)',
        SUM(case FOC_TRANSACTIONCODE when 'XFOOD2' then foc_netamount else 0 end) as 'NetAmount(XFOOD2)'

您最好只在表上左键连接，在新的extras表上左键连接，然后旋转出所需的列

如果在没有修改数据库的情况下运行它，我会感到非常惊讶，因为除了重新创建表之外，我无法对它进行测试，但它应该会让您知道如何继续
