[AccessD] DAO Recordset question asked, answered, and misplaced.

[Arthur Fuller]

Thanks, Stuart. There are some snippets in the code that (why, I have no
idea, since I didn't write it) that in the event that no records match, do
an Insert with a dummy record. So perhaps I can reverse-engineer this SQL
ssring and at least get close to what is supposed to be in there. I shall
start there.
