Question

我已经查看了之前的几个问题，但我很难将解决方案应用到我的具体示例中。

我在查询1和查询2时遇到问题。

我的查询最初返回（在其他详细信息中）当前的所有成员/用户的值“ SpentTotal ”和“ UnderSpent ”一个月。

我的问题是在这个原始的quert中添加了两个额外的列，它们将返回JUST这两列（Spent和Overspent），但是对于之前的月数据

原始查询＃1：

set @BPlanKey = '##CURRENTMONTH##'
EXECUTE @RC = Minimum_UpdateForPeriod @BPlanKey

SELECT cm.clubaccountnumber, bp.Description , msh.PeriodMinObligation,  msh.SpentTotal, msh.UnderSpent, msh.OverSpent, msh.BilledDate, msh.PeriodStartDate, msh.PeriodEndDate, msh.OverSpent 
FROM MinimumSpendHistory msh 
     INNER JOIN BillPlanMinimums bpm ON msh.BillingPeriodKey = @BPlanKey and bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey 
     INNER JOIN BillPlans bp ON bp.BillPlanKey = bpm.BillPlanKey 
     INNER JOIN ClubMembers cm ON cm.parentmemberkey is null and cm.ClubMemberKey = msh.ClubMemberKey 
order by cm.clubaccountnumber asc, msh.BilledDate asc

查询＃2，查询PREVIOUS月的所有列，但我只需要两个（花费和花费过多），从上面添加到查询中，加入客户编号：

set @BPlanKeyLastMo = '##PREVMONTH##'
EXECUTE @RCLastMo = Minimum_UpdateForPeriod @BPlanKeyLastMo

SELECT cm.clubaccountnumber, bp.Description , msh.PeriodMinObligation, msh.SpentTotal, msh.UnderSpent, msh.OverSpent, msh.BilledDate, msh.PeriodStartDate, msh.PeriodEndDate, msh.OverSpent 
FROM MinimumSpendHistory msh 
     INNER JOIN BillPlanMinimums bpm ON msh.BillingPeriodKey = @BPlanKeyLastMo and bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey 
     INNER JOIN BillPlans bp ON bp.BillPlanKey = bpm.BillPlanKey 
     INNER JOIN ClubMembers cm ON cm.parentmemberkey is null and cm.ClubMemberKey = msh.ClubMemberKey 
order by cm.clubaccountnumber asc, msh.BilledDate asc

非常感谢任何愿意提供帮助和时间的人。

干杯！

Answer 2

几乎可以肯定有更简单的方法，但这可能有用：

如果ClubAccountNumber在ClubMembers上不是唯一的，您还需要选择此表的主键并加入两个子选项。

Select
  a.ClubAccountNumber, 
  a.Description,
  a.PeriodMinObligation,
  a.SpentTotal,
  a.UnderSpent, 
  a.OverSpent, 
  a.BilledDate, 
  a.PeriodStartDate, 
  a.PeriodEndDate, 
  a.OverSpent, -- this second instance of overspent is from the question...
  b.SpentTotal As LastMonthSpentTotal, 
  b.UnderSpent As LastMonthUnderspent
From (
  Select
    cm.ClubAccountNumber, 
    bp.Description,
    msh.PeriodMinObligation,
    msh.SpentTotal,
    msh.UnderSpent, 
    msh.OverSpent, 
    msh.BilledDate, 
    msh.PeriodStartDate, 
    msh.PeriodEndDate
  From
    MinimumSpendHistory msh 
      Inner Join
    BillPlanMinimums bpm 
      On msh.BillingPeriodKey = @BPlanKey And bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey 
      Inner Join
    BillPlans bp 
      On bp.BillPlanKey = bpm.BillPlanKey
      Inner Join
    ClubMembers cm 
      On cm.ParentMemberKey Is Null And cm.ClubMemberKey = msh.ClubMemberKey 
  ) a Left Outer Join (
  Select 
    cm.ClubAccountNumber,
    msh.SpentTotal,
    msh.UnderSpent
  From
    MinimumSpendHistory msh 
      Inner Join
    BillPlanMinimums bpm 
      On msh.BillingPeriodKey = @BPlanKeyLastMo and bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey
      Inner Join
    BillPlans bp 
      On bp.BillPlanKey = bpm.BillPlanKey 
      Inner Join
    ClubMembers cm 
      On cm.ParentMemberKey Is Null And cm.ClubMemberKey = msh.ClubMemberKey 
  ) b On a.ClubAccountNumber = b.ClubAccountNumber -- this should probably join on cm.clubmemberkey, but we are guessing
Order By
  a.ClubAccountNumber, 
  a.BilledDate

在同一个表上组合两个查询
