Sorry - don't understand. Assuming your values are the right type for the
columns that looks OK to me.

Don't try and put bad data into the batch. It's designed so that if you
automate importing batches of data the operation isn't left in some half-done
state.

Sounds like you want to write a small Perl script to take your data, strip out
anything obviously bad and then insert it in batches. If you have a lot of
bad data you can do it one row at a time, if not transactions of say 100 rows
at a time might be better.
