delete duplicate recore

hi all
if you have a unique key with col1 + col1, you can use following sql.

delete from table_name a
where a.rowid > (select min(b.rowid) from table_name b

                           where b.col1  =  a.col1
                               and b.col2 = a.col2 )

if you have any questions, feel free let me know. bye
