For this question you have to ask clearly is that data
wants to load fresh or they want to load override ,Or is it
same data next time also getting 5 million records .If we
getting same records again 5 million records then use Mload
utility
1) write 2 staments in mload 1st insert into temp table
then again temp table to select only 4th column and insert
into original table(select 4 column) this is one type of
procedure.
2) Then again load by using fast load it will not takes big
time.
