我需要在同一日期获得每个SSN的SUM（费用）。例如来自

302609074,20180215,4002,1001,25,35
302609074,20180215,4006,1003,40,100

我想从日期20180215的表格诊断中获取总和（费用）= 60 + 147 = 207

到目前为止，我没有尝试过任何方法。例如，我得到了：

ELECT Z.date, Z.ssn, TotalCharges
FROM (  
        (SELECT ssn,date,scode,dcode
         FROM outcome
        ) Z
        JOIN 
        (SELECT scode, dcode, charge, SUM(charge) TotalCharges
         FROM diagnosis
        ) U
        ON (U.scode = Z.scode AND U.dcode = Z.dcode)
     )
     GROUP BY Z.date, Z.ssn;

并收到错误ORA-00937：不是单组分组功能

Answer 1

为什么要使用这么多子查询？

SELECT o.date, o.ssn, SUM(d.charge)
FROM outcome o JOIN
     diagnosis d
     ON d.scode = o.scode AND d.dcode = o.dcode
GROUP BY o.date, o.ssn;

如果GROUP BY在子查询中，您的查询也可能会起作用。
