根据位置（状态）查询总和数

Question

我试图编写一个查询，总结2013日历年期间执行的所有程序，无论事件是发生在移动硬盘上还是发生在特定州内的固定网站上。

每个云端硬盘都是唯一的，可以在固定网站（CenterID）或移动网站上进行，这些网站与帐户（AccountID）相关联。我的查询如下：

select sum(proceduresperformed), sum(productscollected)
from DriveProjectionAndCollectedTotals DPaCT
inner join rpt_DriveMaster DM on DPaCT.DriveID=DM.DriveID
left outer join rpt_Accounts Acct on DM.AccountID=Acct.AccountID
left outer join rpt_CenterDetail CD on DM.CenterID=CD.CenterID
inner join rpt_AddressDetail AD on Acct.AccountID=AD.AccountID
inner join rpt_AddressDetail AD2 on CD.CenterID=AD2.CenterID
where AD.State='FL'
or AD2.State='FL'
and Year(DM.FromDateTime)=2013

但这些数字真的很高且不正确。所以我做的是删除其中一个连接（Account或CenterDetail）并运行查询两次以获得看起来更符合预期的数字：

select sum(proceduresperformed), sum(productscollected)
from DriveProjectionAndCollectedTotals DPaCT
inner join rpt_DriveMaster DM on DPaCT.DriveID=DM.DriveID
left outer join rpt_Accounts Acct on DM.AccountID=Acct.AccountID
--left outer join rpt_CenterDetail CD on DM.CenterID=CD.CenterID
inner join rpt_AddressDetail AD on Acct.AccountID=AD.AccountID
--inner join rpt_AddressDetail AD2 on CD.CenterID=AD2.CenterID
where AD.State='FL'
--or AD2.State='FL'
and Year(DM.FromDateTime)=2013

如何修复原始查询，以基本上不会使预期值增加三倍的方式汇总这两列？

原始查询返回：

并分别使用帐户和中心运行查询：

我回去并使用UNION声明给我正确答案：

select sum(procperf) as 'Procedures Performed'
from (
select sum(proceduresperformed) as procperf
from DriveProjectionAndCollectedTotals DPaCT
inner join rpt_DriveMaster DM on DPaCT.DriveID=DM.DriveID
left outer join rpt_Accounts Acct on DM.AccountID=Acct.AccountID
inner join rpt_AddressDetail AD on Acct.AccountID=AD.AccountID
where AD.State='FL'
and Year(DM.FromDateTime)=2013
UNION
select sum(proceduresperformed) as procperf
from DriveProjectionAndCollectedTotals DPaCT
inner join rpt_DriveMaster DM on DPaCT.DriveID=DM.DriveID
left outer join rpt_CenterDetail CD on DM.CenterID=CD.CenterID
inner join rpt_AddressDetail AD2 on CD.CenterID=AD2.CenterID
where AD2.State='FL'
and Year(DM.FromDateTime)=2013
) as a;
