I assumed that you mean that the input file can have more fields in it than are required by the sql, and that they may not always be in the same order.
I tried doing the following with a comma delimited input file but I could not get it to work, but it does work with a space or tab delimited file.
I found a use for this, as I have a client that sends us an excel file that we convert to csv and invariably there are extraneous columns in the file.
Code:
# cat vinus4
