关于oracle中数据重复的问题，在线等高人解答

这个是日志里面报错的：
[2011-11-03 03:44:17] Error: 
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "WZ_NOK_OMCR4_UPLOAD.NC_UPLOAD_BTS_OTHER_INFO", line 31
ORA-06512: at line 1

其中报错的sql语句为：
SELECT obj_inst INTO v_bts_inst FROM syn_dic_obj_inst
  WHERE dist_id = p_dist_id AND net_id = p_net_id AND prod_id = p_prod_id AND
  class_id = p_bts_class_in_nmc AND obj_name like '%'|| v_cell_id;

我把syn_dic_obj_inst这个表的数据重复查过了，没有发现重复，我百度搜索，有人说是游标里面有重复，我也将处理加在了游标的下面，在线等人解决！

有木有人在啊，在线等高手解答啊！

有重复数据，但是你只要随便一条数据都可以的话，你就加一个 where rownum = 1
或者把 select into 这个改为用游标，然后循环读数据继续处理

佩服你的耐心。。。那么长的文档。。。

正解
SELECT obj_inst INTO v_bts_inst FROM syn_dic_obj_inst
  WHERE dist_id = p_dist_id AND net_id = p_net_id AND prod_id = p_prod_id AND
  class_id = p_bts_class_in_nmc AND obj_name like '%'|| v_cell_id;
你这里的obj_inst值有多条记录，然后你把它放到一个变量里就报错了，
open test_cursor for SELECT obj_inst FROM syn_dic_obj_inst
  WHERE dist_id = p_dist_id AND net_id = p_net_id AND prod_id = p_prod_id AND
  class_id = p_bts_class_in_nmc AND obj_name like '%'|| v_cell_id;

但是我查询游标里面的数据，并没有发现重复额，我是按照lac_id, cell_id来分组的。

我现在就是不知道，到底是游标里面有重复数据还是错误sql中的表里面有重复数据。因为两个方面我都查了重复，但是没发现有重复。

你能确信 v_lac_id 是不会重复的吗？

SQL code

delete from nok_bts_con_temp a
  where a.rowid >(select min(rowid) from nok_bts_con_temp b
  where a.cell_id=b.cell_id);

FETCH c_bts_code INTO v_lac_id, v_cell_id;

update 语句也会引起 too_many_rows 错误的
你看一下你 update 语句后的 select 语句是否只返回一行数据

delete from nok_bts_con_temp a
  where a.rowid >(select min(rowid) from nok_bts_con_temp b
  where a.cell_id=b.cell_id);
   
  DELETE FROM syn_dic_obj_inst
  WHERE OBJ_INST IS NULL ;
，这段sql已经加到了那里面了，有重复也在游标打开之前就处理了。

额，其实我也在想，就是重复会不会是其他的语句的，我想把后面的update语句都给查一遍

你用 plsql developer 工具，单步调试一下存储过程，看是哪一步出的错，然后看一下数据

额，我那个游标里面有1W多条数据的，单步调试等一个多小时吧，我把下面全部的表给查一遍也不过那么多时间了，看看还有其他朋友能指点没，没有的话，就只能用这个方法了。哎。

plsql test 调试界面有一个“红色小方框”按钮，点一下，直接到报错行
你把报错行语句拷贝出来执行，然后再看数据

哦哦，行，先谢谢你了啊，我先去吃饭了，等下回来再试试。
