如何删除Access表中多余的重复记录（多个字段），只留有rowid最小的记录

Answer 1

delete from vitae a
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 vitae group by peopleId,seq having count(*)>1)

Answer 2

其实不用那么复杂。你可以将WHERE条件加到两个select语句上就可以了，而且比较简单易于理解。
