open cur_rows
3、查找表中多余的重复记录（多个字段）
如果还查性别也相同大则如下:
2、删除表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断，只留有rowid最小的记录
and rowid not in (select min(rowid) from vitae group by peopleId,seq having count(*)>1)
Select Name,Count(*) from A Group By Name Having Count(*) > 1
方法一
比方说
在A表中存在一个字段“name”，
而且不同记录之间的“name”值有可能会相同，
5、查找表中多余的重复记录（多个字段），不包含rowid最小的记录
select * from vitae a
(三)
4、删除表中多余的重复记录（多个字段），只留有rowid最小的记录
and rowid not in (select min(rowid) from vitae group by peopleId,seq having count(*)>1)
declare cur_rows cursor local for select 主字段,count(*) from 表名 group by 主字段 having count(*) >； 1
where peopleId in (select   peopleId from   people group by   peopleId having count(peopleId) > 1)
查询及删除重复记录的SQL语句
delete from people
where peopleId in (select   peopleId from people group by   peopleId   having count(peopleId) > 1)
fetch cur_rows into @id,@max
Select Name,sex,Count(*) from A Group By Name,sex Having Count(*) > 1

select * from people
where (a.peopleId,a.seq) in   (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
 
while @@fetch ...... where (a.peopleId,a.seq) in   (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
where (a.peopleId,a.seq) in   (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
and rowid not in (select min(rowid) from   people group by peopleId having count(peopleId )>1)
select * from vitae a
现在就是需要查询出在该表中的各记录之间，“name”值存在重复的项；
declare @max integer,@id integer
注:rowid为oracle自带不用该.....
