无效的ID上更新（甲骨文）

Question

我尝试执行以下命令：

UPDATE DB_TEST.STOCK_ITEMS 
    SET STATUS = (SELECT * 
        FROM (SELECT STOCK_ITEM_STATUS 
          FROM DB_TEST.STOCK_ITEMS_HISTORY 
          WHERE STOCK_ITEM_ID = DB_TEST.STOCK_ITEMS.ID 
          ORDER BY CHANGED_ON DESC, ID DESC) 
        WHERE ROWNUM <= 1) 
WHERE EXISTS (SELECT * 
       FROM DB_TEST.STOCK_ITEMS_HISTORY 
       WHERE STOCK_ITEM_ID = DB_TEST.STOCK_ITEMS.ID); 

但我得到的错误：

SQL-Error: ORA-00904: "DB_TEST"."STOCK_ITEMS"."ID": invalid identifier 

我抬头Oracle错误，但我得到的是，我应该使用错误或缺少列名称，但DB_TEST.STOCK_ITEMS.ID字段肯定存在。

还有什么其他原因会导致此错误？

Oracle将表的范围限制为一个子查询级别。这是解决使用问题的方法keep：

UPDATE DB_TEST.STOCK_ITEMS 
    SET STATUS = (SELECT MAX(STOCK_ITEM_STATUS) KEEP (DENSE_RANK FIRST ORDER BY CHANGED_ON DESC, ID DESC) 
       FROM DB_TEST.STOCK_ITEMS_HISTORY 
       WHERE STOCK_ITEM_ID = DB_TEST.STOCK_ITEMS.ID 
       ) 
    WHERE EXISTS (SELECT 1 
       FROM DB_TEST.STOCK_ITEMS_HISTORY 
       WHERE STOCK_ITEM_ID = DB_TEST.STOCK_ITEMS.ID 
       );
