Hi Stephan, > A query without a group by, in other words one on which the count is done > over the entire set of rows that pass the where clause. OK. > I believe > select count(*) from prototype.customers, prototype.addresses where > customers.contactaddress = addresses.objectid and zipCode < '2716BN'; > will work and give you an overall count. The working query (I did not count if the answer was correct ;-)) appears to be: SELECT COUNT(zipcode) FROM prototype.customers, prototype.addresses WHERE customers.contactaddress = addresses.objectid AND zipCode < '1234ab' -- Groeten, Joost Kraaijeveld Askesis B.V.
