Here is an example of what I mean:

delete from dept_copy
where rowid in
(select rowid from dept_copy
minus
select max(rowid) from dept_copy
group by DEPTNO, DNAME, LOC);

One more time, Assume fld1,fld2,fld3 constitute a unique record

SELECT fld1,fld2,fld3
FROM <table>
GROUP BY fld1,fld2,fld3
HAVING COUNT(*) > 1;

Other ways but this will work

Hi all,

I am sure this question has been asked many times but I don't seems to find
it from archive, here goes again. How do find all the duplicate rows in a
table?
thanks,

WZ
