SELECT DISTINCT B.INSUREDNAME AS INSUREDNAME,A.ACCIDENTNO,
MIN(D.CLAIMCOMCODE) AS CLAIMCOMCODE,
DISTINCT C.MODELNAME AS MODELNAME,
MIN(A.DAMAGESTARTDATE) AS DAMAGESTARTDATE,
MIN(A.DAMAGEADDRESS) AS DAMAGEADDRESS,
DISTINCT C.LICENSENO AS LICENSENO
FROM MID_CAR_LREGIST A,
WEB_LIST_CMAIN B,
ODS_CITEMCAR C,
ODS_CAR_LSURVEY D
WHERE A.ACCIDENTNO ='62016420000041083'
AND A.POLICYNO = B.POLICYNO
AND A.POLICYNO = C.POLICYNO
AND A.ACCIDENTNO = D.ACCIDENTNO
AND A.CANCELDATE IS NULL
GROUP BY A.ACCIDENTNO, A.CLAIMCOMCODE;

Answer 1

首先说Group By，你用了min()函数，上面没有使用聚合函数的字段都需要加在Group By后面进行分组。而你只加了两个，其中A.CLAIMCOMCODE
写法还是错的，再说你SQL语句，你这样查如果B表，C表中POLICYNO为外键且有多个，你查出来了的条数就不是唯一的了
