获取SQL错误：ORA-00904：“STATUS”：在oracle中使用join时标识符无效

Question

当我使用update在Join查询下方触发时，我收到以下错误。请帮我解决这个问题。

  

SQL错误：ORA-00904：“STATUS”：标识符无效   00904. 00000 - “％s：无效标识符”

查询是：

UPDATE (
    SELECT
        a.COLUMN_35,
        a.network_nni 
    FROM 
        Table_1 a
    JOIN Table_2 b 
    ON a.COLUMN_35 = b.COLUMN_35
    AND a.network_id = b.network_id
    WHERE b.COLUMN_35 IS NOT NULL
    AND a.status = 'Status_1'
)
SET status = 'Status_2'; 

请检查并最早建议。

您需要更新a.status列，以便在select语句中选择该列

尝试以下查询

 update 
   (select a.status as Stat
   from Table_1 a
   JOIN  Table_2 b ON
   a.COLUMN_35=b.COLUMN_35
   and a.network_id= b.network_id
   where b.COLUMN_35 is not null
  and a.status='Status_1') b
 set b.stat = 'Status_2';
