Subj:   Re: Inner joins and missing data
 
From:   Coffing Christopher L

Use and outer join instead and you will always return data from the driver table. With an inner join you will only return data that has a match.

The LEFT outer join will return all rows from the left table and null from the other tables joining to it if there is not a match.

You can filter out any rows that you do not want using a where clause.
