我需要每个＆＃34;总和＆＃34;成为别名...这可能吗？

如

( sum(case when ( LNDSpace.UW_Review_Ticket.Loan_Type )='VA' and (   LNDSpace.UW_Review_Ticket.Review_State )='New' and ( LNDSpace.UW_Review_Ticket.Review_Type ) in ('Appraisal / LAPP') 
and  ( LNDSpace.UW_Review_Ticket.SH_2R_Denial )='No' and ( LNDSpace.UW_Review_Ticket.SH_Appeal )='No' and ( LNDSpace.UW_Review_Ticket.Decision )<>'Withdrawn' then 1 else 0 end ) as TEST1)

使用派生表，您可以将此总和作为别名...

SELECT q1.reportdate
    ,q1.eid
    ,(cast(totalweight AS DECIMAL(20, 2)) / 60)

        ,(
            DT.sum1 +
