oracle怎么核对两个表的数据是不是一致

Posted 2023-05-08

参考技术A 例如：核对web层和mid层保费收入的差异：
首先把这两个模块看做两张表，而且这两个模块出的字段一致，需要编号和钱，核对这个钱的数据为啥不对。
①WEB层
SELECT SUM(A.PREMIUMCNY) "保费收入(含税) "
FROM WEB_XG_SALESMAN_RISK_ALL A
WHERE TRUNC(A.STATDATE) BETWEEN DATE '2019-09-01' AND DATE '2019-09-30';
②MID层
SELECT SUM(NVL(A.PREMIUM, 0)) AS 保费收入
FROM MID_CB_PREMIUM_RISK_ALL A
WHERE TRUNC(A.STATDATE) BETWEEN DATE'2019-09-01' AND DATE'2019-09-30';
----------------------------------------------------------------------------------------
结果：（需要把两个模块的编号 和 钱 都写出来）
SQL：
SELECT A.POLICYNO, --编号
SUM(A."保费收入(含税) ") AS BFSRHS,
B.POLICYNO,
SUM(B.保费收入) AS BFSR
FROM
(SELECT A.POLICYNO,SUM(A.PREMIUMCNY) "保费收入(含税) "
FROM WEB_XG_SALESMAN_RISK_ALL A
WHERE TRUNC(A.STATDATE) BETWEEN DATE '2019-09-01' AND DATE '2019-09-30'
GROUP BY A.POLICYNO
) A
FULL JOIN
(SELECT A.POLICYNO,SUM(NVL(A.PREMIUM, 0)) AS 保费收入
FROM MID_CB_PREMIUM_RISK_ALL A
WHERE TRUNC(A.STATDATE) BETWEEN DATE'2019-09-01' AND DATE'2019-09-30'
GROUP BY A.POLICYNO
) B
ON A.POLICYNO = B.POLICYNO --用编号关联
WHERE A.POLICYNO IS NULL OR B.POLICYNO IS NULL --是否一致
OR A.BFSRHS <> B.BFSR
group BY A.POLICYNO,
B.POLICYNO 参考技术B Oracle中比对2张表之间数据是否一致的几种方法

在ORACLE中，如何比较两个表的数据是否相同，查询两个表内容不一致的内容

在ORACLE中，如何比较两个表的数据是否相同

 

比如A表的m列z有值（1,2,3,4,5），B表的n列有值（3,4,5,6,7,8）。要查找出（3,4,5,）三个值。

 

select t1.* from
(select LCH,LGH from SJCJ_GLTSHY where JLSJ >=to_date(‘2020-05-12 00:00:00‘, ‘yyyy-mm-dd HH24:MI:SS‘)
minus
select LCH,LGH from SJCJ_GLTSHY_BAK where JLSJ >=to_date(‘2020-05-12 00:00:00‘, ‘yyyy-mm-dd HH24:MI:SS‘)) t1
union 
select t2.* from
(select LCH,LGH from SJCJ_GLTSHY_BAK where JLSJ >=to_date(‘2020-05-12 00:00:00‘, ‘yyyy-mm-dd HH24:MI:SS‘)
minus
select LCH,LGH from SJCJ_GLTSHY where JLSJ >=to_date(‘2020-05-12 00:00:00‘, ‘yyyy-mm-dd HH24:MI:SS‘)) t2
