Is it possible to form a query where table1.first_name + " " + table1.last_name matches table2.customer_name?
IE: customers.first_name = "John" customers.last_name = "Doe"
orders.customer_name = "John Doe"
It seems to me this would be a common query, but just can't come up with the syntax intuitively...

... WHERE table1.first_name || " " || table1.last_name = table2.customer_name

Evidently I'm a wee bit rusty on SQL syntax, but your solution worked like a champ, so a 1000 thanks!!!
I went with:
SELECT *
FROM customers, sales
WHERE customers.first_name || " " || customers.last_name = sales.customer_name
ORDER BY sales.id;
It worked as I intended!
Thanks again!
