The INNER query returns only rows that have a match on both sides of the JOIN.

You can use a OUTER join to return all rows from one side (LEFT or RIGHT) and matching rows from the otherside.

SELECT DayTrans.*, Customer.Address
FROM DayTrans LEFT OUTER JOIN Customer
ON DayTrans.CustCode = Customer.CustCode

For those record of DayTrans that don't have matching CustCode in Customer, NULL will be placed in Address.
