Solution

The correct answer is Full outer join

Key PointsA "Full Outer Join" (also known as Full Join) is used in SQL to combine rows from two or more tables based on a related column. The outcome of a Full Outer Join includes all the records from both the left and the right tables, and it matches rows from both tables where the join condition is met. If there isn't a match, the result is NULL on either the left or the right side (or both, in case of no common relation).

So the correct answer is Full outer join

Additional Information

• A NATURAL JOIN is a type of join operation in SQL that is used to combine rows from two or more tables based on the columns they have in common. This can be particularly useful when you have two tables that contain related data, but do not have an explicitly defined foreign key relationship.
• Unlike other join types, NATURAL JOIN doesn't require a specific condition to match columns from one table with another, as it automatically matches columns with the same name in both tables. For example, if both tables have a column named 'customer_id', the NATURAL JOIN will use this column as the join condition.
