问题描述：
ORACLE关于merge into用法!
MERGE INTO MSA2008BS.ATYW_ZS_GCZL A
USING (SELECT * fROM LOADTMP.MSA2008BS_ATYW_ZS_GCZL WHERE ETL_F IN ('I','D','A')) B
ON (A.ATZSCZLOID=B.ATZSCZLOID)
WHEN MATCHED AND B.SHIPFID ='' THEN UPDATE SET
A.SHIPFID =B.SHIPFID ,
A.GCZLDJZHM=B.GCZLDJZHM ,
A.CBDJH =B.CBDJH
WHEN NOT MATCHED THEN
INSERT(A.ATZSCZLOID,A.SHIPFID,A.GCZLDJZHM,A.CBDJH,A.CBCZR)
VALUES(B.ATZSCZLOID,B.SHIPFID,B.GCZLDJZHM,B.CBDJH,B.CBCZR)
;
中因为在WHEN MATCHED后加入了AND条件即：AND B.SHIPFID =''
之后报错,是不是oracle不支持WHEN MATCHED后跟条件呢?
