SQL-同一列中的费用和付款;如何打破它

Question

我有一个SQL查询，它正在从多个表中提取数据（我有11个加入）

有一个" artransaction"表，其中包含电荷，付款，调整等。并且其中有一个" TrassActionCodeid"列，其中描述了交易类型。

我正在尝试选择大量数据，但需要两个单独的列（上面有注释），一个用于费用，另一列用于付款。有没有办法在不使用Where子句的情况下实现这一目标？我尝试使用嵌套的选择语句，但它返回了每个行的相同值（总数）

我正在附上以下查询 - 预先感谢！同样，我是数据检索的新手，因此，如果其他任何事情看起来很不奇怪，其他任何建议都非常感谢。

SELECT CONVERT(varchar(10),sl.ServiceDtFrom, 101) AS 'srvdate'
     , f.Alias AS 'svc dprtmnt'
     , CASE WHEN pc.Alias IS NULL
            THEN po.Name
            ELSE pc.Description END AS 'svc dept grp'
     , COUNT(clm.ID) AS 'clm cnt'
     , COUNT(p.ID) AS 'ptnt count'
     /* 1 */ 
     , SUM(ar.Amount) AS 'all chgs' --ONLY CHARGES (tt.ID IN(1,2))
     , SUM(sl.Units + sl.TimeUnits + sl.PhysicalStatusUnits) AS 'chg units sum'
     /* 2 */ 
     , SUM(ar.Amount) AS 'net pmt'  --ONLY PAYMENTS (tt.ID IN(3,4,9,10,11,12,20,21))
FROM ARTransaction ar           WITH (NOLOCK)
LEFT JOIN ServiceLine sl        WITH (NOLOCK)
    ON ar.ServiceLineID = sl.ID
LEFT JOIN Incident i            WITH (NOLOCK)
    ON sl.IncidentID = i.ID
LEFT JOIN HealthCareFacility f  WITH (NOLOCK)
    ON i.FacilityID = f.ID
LEFT JOIN ProvOrgFacility poc   WITH (NOLOCK)
    ON poc.FacilityID = f.ID
LEFT JOIN ProfitCenter pc       WITH (NOLOCK)
    ON poc.ProfitCenterID = pc.ID

    ON i.ProvOrgID = po.ID
LEFT JOIN Claim clm             WITH (NOLOCK)
    ON i.ID = clm.IncidentID
LEFT JOIN Person p              WITH (NOLOCK)
    ON i.PatientID = p.ID
LEFT JOIN TransactionCode tc    WITH (NOLOCK)
    ON ar.TransactionCodeID = tc.ID
LEFT JOIN TransactionType tt    WITH (NOLOCK)
    ON tc.TransactionTypeID = tt.ID
WHERE i.IsReversed <> 1
      AND sl.ServiceDtFrom IS NOT NULL
GROUP BY
      sl.ServiceDtFrom, f.Alias
    , po.Name, pc.Alias, pc.Description
ORDER BY 1,3,2

您可以使用案例语句来实现这一目标： -

SELECT CONVERT(varchar(10),sl.ServiceDtFrom, 101) AS 'srvdate'
     , f.Alias AS 'svc dprtmnt'
     , CASE WHEN pc.Alias IS NULL
            THEN po.Name
            ELSE pc.Description END AS 'svc dept grp'
     , COUNT(clm.ID) AS 'clm cnt'
     , COUNT(p.ID) AS 'ptnt count'
     /* 1 */ 
     , SUM(case when tt.ID IN(1,2) then ar.Amount else 0 end) AS 'all chgs' --ONLY CHARGES (tt.ID IN(1,2))
     , SUM(sl.Units + sl.TimeUnits + sl.PhysicalStatusUnits) AS 'chg units sum'
     /* 2 */ 
     , SUM(case when tt.ID IN(3,4,9,10,11,12,20,21) then ar.Amount else 0 end) AS 'net pmt'  --ONLY PAYMENTS (tt.ID IN(3,4,9,10,11,12,20,21))
FROM ARTransaction ar           WITH (NOLOCK)
LEFT JOIN ServiceLine sl        WITH (NOLOCK)
    ON ar.ServiceLineID = sl.ID
LEFT JOIN Incident i            WITH (NOLOCK)
    ON sl.IncidentID = i.ID
LEFT JOIN HealthCareFacility f  WITH (NOLOCK)
    ON i.FacilityID = f.ID
LEFT JOIN ProvOrgFacility poc   WITH (NOLOCK)
    ON poc.FacilityID = f.ID
LEFT JOIN ProfitCenter pc       WITH (NOLOCK)
    ON poc.ProfitCenterID = pc.ID
LEFT JOIN ProviderOrganization po WITH (NOLOCK)
    ON i.ProvOrgID = po.ID
LEFT JOIN Claim clm             WITH (NOLOCK)
    ON i.ID = clm.IncidentID
LEFT JOIN Person p              WITH (NOLOCK)
    ON i.PatientID = p.ID
LEFT JOIN TransactionCode tc    WITH (NOLOCK)
    ON ar.TransactionCodeID = tc.ID
LEFT JOIN TransactionType tt    WITH (NOLOCK)
    ON tc.TransactionTypeID = tt.ID
WHERE i.IsReversed <> 1
      AND sl.ServiceDtFrom IS NOT NULL
GROUP BY
