Start by creating an ordinary select query, and specify the criteria, e.g.
in the criteria row of your "firstfield" column the expression would look
like =[secondfield]. Switch to datasheet view to make sure that it displays
only the records you want to delete. Then go back into design view and
choose Delete Query from the Query menu.

The spammers and script-kiddies have succeeded in making it impossible for
me to use a real e-mail address in public newsgroups. E-mail replies to
this post will be deleted without being read. Any e-mail claiming to be
from brenreyn at indigo dot ie that is not digitally signed by me with a
GlobalSign digital certificate is a forgery and should be deleted without
being read. Follow-up questions should in general be posted to the
newsgroup, but if you have a good reason to send me e-mail, you'll find
a useable e-mail address at the URL above.
