May I know that how can i delete duplicate records without using rowid and how many ways to find duplicate records?
Kindly share your valuable views here.
Thanks in advance.
You can use this query also : delete from <table1> where <key column> in (select <key column> from <table1> group by <key column> having count(*) >1)
Use simple Union clause to delete duplicate records if you do not want to use row id for eaxmple select dept no from emp union select dept no from emp.
