Can you modify the 'extract' and make the extra column "\n" which is the
null escape?

That would be the only other option.

I would rather not do it this way as I use the same load script at all=20
customer sites where the extracts and requirements may vary. I.e. one=20
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=20
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=20
  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=20
with several hundred columns... your suggestion would be a bit=20
cumbersome - particularly if it is only one or two columns in each table =

that that the client doesn't need.
