Customer Master File

Phone #

Customer Charge Detail file

Phone #
Charge code

Charge code master

Charge code
Group code

Easy enough to find all customers who have a specific charge code or a
specific group (i.e. we may have 3 charge codes, one for employees, one
for business, one for residence) that all signify touch tone service, so
search using group code = TONE


Up till now I have been doing it in multiple steps in queries (i.e. step
1 - find all customers with the charge code/group code - output to file

Step 2 compare cust master phone # to output file in step 1 list/output
all non matches

How do I convert this to a single SQL statement, I've looked and looked
and I JUST DON'T SEE IT!!!!
