ora-00904 无效的标识符

ora-00904 :"B"."TT_ROW_ID":无效的标识符 请专家帮忙看下,谢谢啦

CREATE OR REPLACE VIEW V_WIRE_APPROVE AS
SELECT A.ROW_ID,
  DECODE(A.NUM1, '0', '未审批', '1', '已审批', '2', '审批中', A.NUM1) CMCHECKFLG,
  B.TYPENAME,
  B.STEPNUM,
  B.TIMELIMIT,

  AND (STEPNUM = 1 OR EXISTS  
  (SELECT 1
  FROM (SELECT ISACCOUNT, STEPNUM
  FROM HJBO_WIRE_APPROVE

  WHERE C.ISACCOUNT = '1'
  AND C.STEPNUM = B.STEPNUM - 1))
  AND A.STR2 = '1'
  AND B.ISACCOUNT IS NULL;

SQL code

(SELECT 1
  FROM (SELECT ISACCOUNT, STEPNUM
  FROM HJBO_WIRE_APPROVE
  WHERE TT_ROW_ID = B.TT_ROW_ID) 
--这块这样写就行：
(SELECT 1 FROM HJBO_WIRE_APPROVE
 WHERE TT_ROW_ID = B.TT_ROW_ID)

并且确认一下在表HJBO_WIRE_APPROVE中是否有TT_ROW_ID字段。

不要重复发帖哦。最外层的表B 隔了2层是找不到的。

到这个里面 
(SELECT ISACCOUNT, STEPNUM
  FROM HJBO_WIRE_APPROVE
  WHERE TT_ROW_ID = B.TT_ROW_ID)
  B是无法识别的
