the matches from each table.
An outer join returns a set of records (or rows) that include
what an inner join would return but also includes other rows
for which no corresponding match is found in the other table.
Includes left outer join, which returns all records from the left
table (table1), and the matched records from the right table
(table2). The result is NULL from the right side, if there is no
match.
Also includes right outer join, which would include all records
