oracle 报错 column ambiguously defined

column ambiguously defined

ORA-00918: column ambiguously defined

java.sql.SQLException: ORA-00918: column ambiguously defined
ORA-00918: column ambiguously defined。中文名称：未明确定义的列！

可能定义了两个相同的列

你找找你后面的t里面是不是有两个相同的列,我也是这个问题,就是多了一个相同的列的查询,所以sb了..

我出错的sql语句是

select *

  from (select rownum as seq, t.*

          from (select item_code,

                       item_abv,

                       order_no,

                       unit_name,

                       assist_unit_name,

                       mb_qty,

                       inspection_qty,

                       mi_qty,

                       assist_mi_qty,

                       mo_qty,

                       assist_mo_qty,

                       on_hand_qty,

                       assist_qty,

                       ma_qty,

                       assist_ma_qty

                       assist_ma_qty -- 这一行出错了,列写重复了(删掉 运行,就ok啦)

                        -- assist_ma_qty as assist_ma_qty2 -- 不想删掉就这样写

                  from inv_book_master) t

         where rownum <= 10)

 where seq > 0

或者你参考 我的另一个帖子，教你怎么换一种方式rownum 分页，http://hi.baidu.com/ae6623/item/aaa12115f2e4ca09e75c3635
