Hi
Table A got some duplicated rows.. The requirement is to delete the
duplicate records by maintaing one copy..
Is it manageable thru single query? or have to go for PL/SQL procedure?
Pl. send me ur valuable inputs.

Please see the official ORACLE-L FAQ:
I think this query eliminates the duplicated rows:
delete from table_name where rowid not in (select maxrowid from (select
column1,column2, max(rowid) maxrowid from den group by column1,column2));

I am sorry I made a mistake in naming . Correct one is below:
delete from table_name where rowid not in (select maxrowid from (select
column1,column2, max(rowid) maxrowid from table_name group by
column1,column2));
