我需要在同一日期獲得每個SSN的SUM（費用）。 例如來自

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

我想從日期20180215的表格診斷中獲得總和（charge）= 60 + 147 = 207

到目前為止，我沒有嘗試過任何方法。 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;

並收到錯誤ORA-00937：不是單組分組功能

Answer 1

為什么要使用這么多子查詢？

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在子查詢中，則您的查詢也可能起作用。
