Question

DELETE  UserDB..UserAccount
  FROM UserDB..UserAccount A, CustDB..ETS_Profile B  
 WHERE A.UserId = B.User_Id
   and  B.Category = 'Customer'
   AND B.Sub_Category = 'Teir'
   and B.Item_Name = 'CUSTODIAN'

以上是Sybase查询，效果很好。我正在为UserDB创建一个处理程序并在Oracle中执行此查询

在oracle中，如果我提供如下查询，我会收到错误

DELETE UserAccount 
  FROM UserAccount A,CustDB.ETS_Profile B
 where A.UserId = B.User_Id
   and  B.Category = 'Customer'
   and B.Sub_Category = 'Teir'
   and B.Item_Name = 'CUSTODIAN';

Answer 1

您应该按如下方式制定查询：

DELETE FROM UserAccount A
 WHERE EXISTS
       ( SELECT NULL
           FROM CustDB.Ets_Profile B
          WHERE B.user_id = A.UserId
            AND B.Category = 'Customer'
            AND B.Sub_Category = 'Teir'
            AND B.Item_Name = 'CUSTODIAN'
       );

Sybase查询在Oracle中不起作用
