SQL FULL OUTER JOIN
Another type of join is called a
SQL FULL OUTER JOIN. This type of join returns all rows from the LEFT-hand
table and RIGHT-hand table with nulls in place where the join condition is not
met.
Syntax
The syntax for the SQL FULL
OUTER JOIN is:
SELECT columns
FROM table1
FULL [OUTER] JOIN table2
ON table1.column = table2.column;
In some databases, the FULL OUTER
JOIN keywords are replaced with FULL JOIN.
