根據位置（狀態）查詢總數

Question

我正在嘗試編寫一個查詢，以總結2013年日曆年中執行的所有過程，無論事件發生在移動驅動器上還是固定站點特定狀態。

每個驅動器都是唯一的，將發生在與帳戶（AccountID）關聯的固定站點（CenterID）或移動站點上。我的查詢是這樣的：

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 

但是，這些數字真的很高，不正確。所以我所做的就是刪除連接（無論是賬戶或CenterDetail）之一，並運行查詢兩次拿到看起來更符合期望是什麼號碼：

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 

如何解決原查詢來總結這兩列的方式基本不會使期望值增加三倍？

原來的查詢返回：

並分別運行與賬戶和中心查詢：

我回去，並使用UNION語句給我正確的答案：

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;
