What is a full join? I've been working with Oracle for 10 years and I've never used that term. I know what a left join is and an outer join, but not a full join.

"Conceptually, a full outer join combines the effect of applying both left and right outer joins. Where records in the FULL OUTER JOINed tables do not match, the result set will have NULL values for every column of the table that lacks a matching row."

It's an outer join.
