【问题描述】：

我似乎找不到查询中缺少的内容：

MERGE INTO Account D
   USING (SELECT       1 AS ID 
                 ,'AAAA' AS NAME
                ,'123Z4' AS GUID
                     , 1 AS STATUS 
          FROM DUAL
         ) S
   ON (D.GUID  = S.GUID)
   AND (D.Name = S.Name)
   WHEN MATCHED 
   THEN 
   UPDATE SET D.Status = S.Status 
   WHEN NOT MATCHED 
   THEN 
   INSERT (D.Id, D.Name, D.GUID, D.Status)
   VALUES (1 , 'AAAA' , '123Z4' , 1)

它给了我一个错误 ORA-00905: missing keyword。

【问题讨论】：

我认为连接条件需要在一对括号中：ON (D.GUID = S.GUID AND D.Name = S.Name)
该死，成功了！非常感谢！，对不起，我从来没有想到过。

【解决方案1】：

目标表和源查询之间的连接条件需要是一对括号内的“单一”条件：

ON (D.GUID  = S.GUID AND D.Name = S.Name)
