用SQL语句怎么过滤重复数据？

1、查找表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断复制代码代码如下:select * from peoplewhere peopleId in (select peopleId from people group by peopleId having count(peopleId) > 1)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最小的记录复制代码代码如下:delete from people where peopleId in (select peopleId from people group by peopleId having count(peopleId) > 1)and rowid not in (select min(rowid) from people group by peopleId having count(peopleId)>1)
