VLDB, Sequence and Sql*loader

Hi Gurus !
What are the best practises for inserting rows with sql*loader and generating an id for each row (eg: flat file contains 3 column, and destination table contains 4 )

• Is-it possible to generate sequence during the loading ? does it work with direct mode ?
• Should we use sequence ? or is it better to update each row with a number afterwards?

TIA
Philippe
