Ok, if you got this far you must have an idea what im looking for. I have two DB's. I need to query four columns in two tables in two DB's at the same time to produce a list of info in order of address(last part I can do

)example: DB1 has table "customers" with columns, address,cust number, phone. second DB2 has table "site", with columns cust number, amount owed, unique code, last bill date. I need to reference the customer number in both to match to get a result containing, "customer number, address, unique code, and amount owed.
sound easy to anyone?
