使用内部连接更新查询时出现的问题

Question

任何人都可以协助让这一个查询工作。我试图更新表中的一列的状态已经加入到其他表

下面是该查询

update 
(select I.account_id, I.sts, I.name_id, CI.CRM_TYPE, I.comments 
    from PPInters I 
     inner join DW.CUST CT 
     on I.account_id = CT.account_id 
     where 
      I.sts is null 
      AND I.comments IS NOT NULL 
      AND CT.CUSTTYPe = 'INTNL') T 

SET T.STS = 'D' 

WHERE T.account_id IN (2000208927,380166014,190180447,166078041,105029075 ) 

我收到“ORA-01779：不能修改映射到非键的列-preserved表”错误

我想在这里做的是集I.STS =‘d’一段700个记录拉升使用此查询

select I.account_id, I.sts, I.name_id, CI.CRM_TYPE, I.comments 
      from PPInters I 
       inner join DW.CUST CT 
       on I.account_id = CT.account_id 
       where 
        I.sts is null 
        AND I.comments IS NOT NULL 
        AND CT.CUSTTYPe = 'INTNL' 

我很感激

Assumming是account_id在表PPInters主键kolumn，
即它的值唯一地标识该表中的记录：

UPDATE PPInters 
SET STS = 'D' 
WHERE account_id IN (

      select I.account_id 
       /*, I.sts, I.name_id, CI.CRM_TYPE, I.comments */ 
      from PPInters I 
       inner join DW.CUST CT 
       on I.account_id = CT.account_id 
       where 
        I.sts is null 
        AND I.comments IS NOT NULL 
        AND CT.CUSTTYPe = 'INTNL' 

) 
AND account_id IN (2000208927,380166014,190180447,166078041,105029075 )
