This or a variant would take a few minutes, but might be worth it.
Get a function that parses a delimited string and returns a table.
(There's one on Erland's web site.)
For each flat file....
Read the first row, which contains the column names.
Parse that into a table and join it to the system table that
indentifies the columns in the target table, by ordinal position.
Go through that in order and build a "create view" statement that has
the effect of renaming the columns.
Execute the statement, and now you can load into the view directly.
The only external parameters are the associations between flat file
and tables.
