Question

我有这个问题，我只是不确定这是否可行。我仍然是MSSQL的新手。

我想要完成的是在12个月期间和6个月期间显示客户的传记数据和他们的奖励收入，并显示相同的结果，以便在他们自己的专栏中显示总和。

我可以通过单独运行每个查询并更改我的Where条件时间来单独完成此操作，但我无法弄清楚如何为客户获得每列的独立结果。我只是不知道如何使我的where语句仅适用于相加的列。我尝试了第二个12个月列的子查询，但它返回的结果超过1，这是不允许的，我需要多个结果。以下是我到目前为止的6个月和12个月的列，没有子查询，第二个声明：

SELECT distinct dbo.tCustomerCard.Acct, dbo.tCustomer.FirstName, dbo.tCustomer.LastName, dbo.tCustomerAddress.Address1, dbo.tCustomerAddress.Address2, dbo.tCustomerAddress.City, dbo.tCustomerAddress.StateName, dbo.tCustomerAddress.PostalCode, dbo.tCustomerPhone.PhoneNumber, tCustomerEmail.EmailAddress, tCustomerAttributeDtl.BirthDt, tCustomerBalanceDtl.Ptsbal, dbo.tCustomer.ClubState, 
Sum(dbo.1Day.BasePts) as "6mnth_Tier_Points_Earned", Sum(dbo.1Day.BasePts) as "12mnth_Tier_Points_Earned"


FROM dbo.tCustomer (NOLOCK)

join dbo.tCustomerCard 
on dbo.tCustomer.CustomerId = tCustomerCard.CustomerId 

full outer join dbo.tCustomerAddress 
on dbo.tCustomer.CustomerId = tCustomerAddress.CustomerId 

full outer join dbo.tCustomerPhone 
on dbo.tCustomer.CustomerId = dbo.tCustomerPhone.CustomerId 

full outer join dbo.tCustomerEmail 
on dbo.tCustomer.CustomerId = dbo.tCustomerEmail.CustomerId 

full outer join dbo.tCustomerAttributeDtl 
on dbo.tCustomer.CustomerId = dbo.tCustomerAttributeDtl.CustomerId 

full outer join dbo.tCustomerBalanceDtl 
on dbo.tCustomer.CustomerId = dbo.tCustomerBalanceDtl.CustomerId 

full outer join dbo.1Day 
on dbo.tCustomerCard.Customerid = dbo.1Day.CustomerId 


WHERE dbo.tCustomerAddress.ContactTypeId = dbo.tCustomer.MailingContactTypeID

---下面是注释掉的，因为我来回使用这个12个月的列。 - 和dbo.1Day.PeriodBeginDtm＆gt; =（选择convert（varchar（4），getdate（），120））和dbo.1Day.PeriodBeginDtm＆gt; = DATEADD（月，-6，GETDATE（））

group by (dbo.tCustomerCard.Acct), (dbo.tCustomer.FirstName), (dbo.tCustomer.LastName), (dbo.tCustomerAddress.Address1), (dbo.tCustomerAddress.Address2), (dbo.tCustomerAddress.City), (dbo.tCustomerAddress.StateName), (dbo.tCustomerAddress.PostalCode), (dbo.tCustomerPhone.PhoneNumber), (tCustomerEmail.EmailAddress), (tCustomerAttributeDtl.BirthDt), (tCustomerBalanceDtl.Ptsbal), (dbo.tCustomer.ClubState)

您可以像这样使用case表达式：

SELECT distinct 
  cc.Acct, 
  c.FirstName, 
  c.LastName, 
  ca.Address1, ca.Address2, ca.City, ca.StateName, ca.PostalCode, 
  cp.PhoneNumber, ce.EmailAddress, 
  cad.BirthDt, 
  cbd.Ptsbal, c.ClubState, 
  SUM(CASE 
        WHEN d.PeriodBeginDtm > = (select convert(varchar(4), getdate(),120)) 
        THEN d.BasePts 
      ELSE 0 END ) AS "12mnth_Tier_Points_Earned",
  SUM(CASE 
        WHEN d.PeriodBeginDtm > = DATEADD(month, -6, GETDATE()) 
        THEN d.BasePts 
       ELSE 0 END) AS "6mnth_Tier_Points_Earned"
FROM dbo.tCustomer (NOLOCK) AS c
join dbo.tCustomerCard                    AS cc  on c.CustomerId  = cc.CustomerId 
full outer join dbo.tCustomerAddress      AS ca  on c.CustomerId  = ca.CustomerId 
full outer join dbo.tCustomerPhone        AS cp  on c.CustomerId  = cp.CustomerId 
full outer join dbo.tCustomerEmail        AS ce  on c.CustomerId  = ce.CustomerId 
full outer join dbo.tCustomerAttributeDtl AS cad on c.CustomerId  = cad.CustomerId 
full outer join dbo.tCustomerBalanceDtl   AS cbd on c.CustomerId  = cbd.CustomerId 
full outer join dbo.1Day                  AS d   on cc.Customerid = d.CustomerId 
WHERE ca.ContactTypeId = c.MailingContactTypeID 
group by ca.Acct, c.FirstName, c.LastName, 
         ca.Address1, ca.Address2, ca.City, 
         ca.StateName, ca.PostalCode, cp.PhoneNumber, 
         ce.EmailAddress, cad.BirthDt, cbd.Ptsbal, 
         c.ClubState

如何在单独的列中进行两个单独的和结果
