Question

任何人都可以建议如何编写SQL查询以包含多个行中多个字段的总和。我正在使用下面的查询，但它一直说“在选择行中的字段无效，因为它不包含在聚合函数或GROUP BY子句中。”

    Select ClaimId,InternalICN,BilledAmt, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN

任何建议都将不胜感激。谢谢！

Answer 1

BilledAmt不在group by子句中。你必须把它放在那里，或用总和，平均值或其他函数汇总它。

Answer 2

BilledAmt不在聚合查询中。当您使用group by时，您只能选择聚合或group by /

组中的任何字段

Answer 3

根据您的真实需要，您有两种选择：

选项＃1：从BilledAmt

中删除SELECT

Select ClaimId,InternalICN, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN

或

选项＃2：将BilledAmt纳入GROUP BY

Select ClaimId,InternalICN,BilledAmt, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN,BilledAmt
