Answer Posted / czarabid
it's very simple the question is to delete the duplicated
records and it's solution is here
DELETE FROM TABLE_NAME1 t1 WHERE ROWID </> any(SELECT ROWID
FROM TABLE_NAME1 t2 WHERE t1.column1=t2.column1);
this will delete only the redundant records leaving only one
copy of the same records in the table.
If you want to delete all the records which are redundant
then the solution is here
DELETE from table_name1 t1 where rowid <> any (select rowid
from table_name1 t2 where t1.no=t2.no)
