How one deletes duplicate rows is as much a factor of how many duplicates exist as well as just knowing there are duplicate rows in the table. Â It also depends on which of the duplicates should be saved:
SQL> rollback;
Rollback complete.
SQL>Â
SQL> delete from mydupes
 2  where rowid not in (select min(rowid)
 3    from mydupes
 4    group by a, b
 5    having count(*) > 1);
963 rows deleted.

SQL> select a, b, c

In the first case the earliest dated records were preserved, and in the latter case the latest dated records were preserved. Â Knowing WHICH of the duplicates to save is also as important..
