Thanks Arun.
Actually
to_date(to_char(to_date(Column,'dd/mm/yyyy'),'YYYYMMDD'), 'YYYYMMDD') solve the problem
There is one more source field with datetimeformat (dd/mm/yyyy hh:mm:ss) & target field is char type.
How to convert this from datetime to char type? i want it in the same format i.e dd/mm/yyyy hh:mm:ss in target. I tried doing direct mapping & also tried with to_char(column, 'varchar').
both these are resulting in blank record in target for this column.
Thanks,
Pavan.
