Helen (or anyone else that can help) :)
How does the CREATE TABLE <table> EXTERNAL handle importing of records that already exist? Do they get rejected and, if so, does that mean the entire import gets dumped?

OK, forget all that syntax. The nearest equivalent is
CREATE TABLE <table-name> EXTERNAL <filesystem-path-name> (see
LangRef.pdf). Your input file needs to be in fixed field format. This
allows you to query the external data file as though it were a table. You
can, for example, write a stored procedure to massage the data and store it
in any way you like.
