oracle关联更新

 业务场景中需要对特定数据进行关联更新，记录一下关联更新语法：

MERGE INTO fine_record_execute targ
USING (SELECT "id","tname"FROM fine_record_executeWHERE "username" LIKE '%目标人物%'AND "time">='2020-08-03'AND "time"<='2020-08-06'
) msrc ON (msrc."id" = targ."id")
WHEN MATCHED THEN UPDATE
SET targ."param" = msrc."tname"--,targ."consume"=msrc."tname"
--WHEN NOT MATCHED THEN INSERT  
--VALUES (msrc.param, msrc."consume", np.category)  
--WHERE msrc.username NOT LIKE '%目标人物%'
