在ORACLE 11.2.0.3上执行merge into 里面sql 入下形式：
merge into DCDW.t1 Target
using (select Org_code Org_code,
BUSS_DATE,
BUSS_NO,
...
from (SELECT E.BUSS_NO BUSS_NO,
E.Org_code Org_code,
..
FROM DCDW.T E
WHERE
E.MODIFIED_DATE >= IN_BEGIN_DATE
AND E.MODIFIED_DATE <= IN_END_DATE)
group by BUSS_NO,Org_code,BUSS_DATE) Source
ON (Target.ORG_CODE = Source.Org_code and target.BUSS_TYPE = '1' AND target.BUSS_DATE = source.BUSS_DATE AND target.BUSS_NO = source.BUSS_NO)
WHEN NOT MATCHED THEN
INSERT
..
WHEN MATCHED THEN
UPDATE
SET ..；
咋都会错误，在ORACLE 11.2.0.1上执行正常，修改以下sql，在各个版本执行都正常，唯一区别是max（org_code）
erge into DCDW.t1 Target
using (select max(Org_code) Org_code,
BUSS_DATE,
BUSS_NO,
...
from (SELECT E.BUSS_NO BUSS_NO,
E.Org_code Org_code,
..
FROM DCDW.T E
WHERE
E.MODIFIED_DATE >= IN_BEGIN_DATE
AND E.MODIFIED_DATE <= IN_END_DATE)
group by BUSS_NO,BUSS_DATE) Source
ON (Target.ORG_CODE = Source.Org_code and target.BUSS_TYPE = '1' AND target.BUSS_DATE = source.BUSS_DATE AND target.BUSS_NO = source.BUSS_NO)
WHEN NOT MATCHED THEN
INSERT
..
WHEN MATCHED THEN
UPDATE
SET ..；
奇怪得很！make下！
