Sys_Connect_By_Path 在10G 第4版的问题

[summercat]

在10G 10.2.0.4 下查不出数据,但是在 10.2.0.1 中可以
语句如下
Select Sys_Connect_By_Path(ceseid, ',') as OutStr
From (Select Rownum Rid, Rownum + 1 Next_Rid, ceseid, enable
From (select * from PS_Corporate_structure where enable = 0))
Where Rid =
(Select Count(*)
From (select * from PS_Corporate_structure where enable = 0))
Start With Rid = 1
Connect By Prior Next_Rid = Rid

功能就是行转列,等同于
select wmsys.wm_concat(ceseid) from PS_Corporate_structure

想问数据库是不是要打什么补丁??

不需要吧?可能是你得测试数据不一样。或者你测试得时候insert了但是没有commit？

不是的,数据肯定一样了,
问题解决了。

是怎么回事来着？
告诉我们分享下``

[inthirties]

是语句本身的逻辑写错了吧

[summercat]

语句本身逻辑是没问题的,说了在在10G 10.2.0.4 下查不出数据,但是在10G 10.2.0.1 中可以 。
相同的数据结构 相同的数据。

原因

在
10.2.0.4 下 无法正确识别 Rownum + 1 Next_Rid 加括号 加as 都不行,解决办法 还是改这个语句 ,当时相对改的教小了。

Select Sys_Connect_By_Path(ceseid, ',') as OutStr
From (Select Rownum Rid, Rownum + 1 Next_Rid, ceseid, enable
From (select * from PS_Corporate_structure where enable = 0))
Where Rid =
(Select Count(*)
From (select * from PS_Corporate_structure where enable = 0))
Start With Rid = 1
Connect By Prior Next_Rid = Rid

=====>

Select Sys_Connect_By_Path(ceseid, ',') as OutStr
From (Select Rownum Rid, Rownum + 1 Next_Rid, ceseid, enable
From (select * from PS_Corporate_structure where enable = 0))
Where Rid =
(Select Count(*)
From (select * from PS_Corporate_structure where enable = 0))
Start With Rid = 1
Connect By Prior Rid +1 = Rid //这里
