I would rather not do it this way as I use the same load script at all customer sites where the extracts and requirements may vary. I.e. one customer may not use the location field mentioned above, but another might.
What I would prefer to do, if possible, is set that column in the database to 'not required' so that if I get an extract that doesn't have that column in the file, the copy doesn't care.
As it stands now I generally have to drop all the unneeded columns from numerous tables, perform my load and then re-add them back again.
When we're talking about 40 or more tables in each database some tables with several hundred columns... your suggestion would be a bit cumbersome - particularly if it is only one or two columns in each table that that the client doesn't need.
