For simple explanation....

I have two tables with these fields:

MASTER
cname = char

DETAIL
cname = char (match above cname)
dorder = date

I need to create a list of all the MASTER records that DO NOT have a matching record in the detail.
I believe this should be a simple SQL select but I can't figure out how to get the joins / where clause
to work right so that I only get the MASTER records.

HELP!!! Something simple and it's driving me nuts!!!
