Explaining Full Outer Join, Left Outer Join, and Right Outer Join in Oracle

When working with Oracle databases, understanding the differences between a full outer join, left outer join, and right outer join is crucial for efficient query operations.

Full Outer Join

In a full outer join, all matching and non-matching rows from both tables are included in the result set. This means that if there are unmatched rows in either table, they will still appear in the output.

Left Outer Join

A left outer join returns all rows from the left table and the matched rows from the right table. If there are no matching rows in the right table, NULL values are used for those columns.

Right Outer Join

Conversely, a right outer join includes all rows from the right table and the matched rows from the left table. Similar to the left outer join, if there are no matching rows in the left table, NULL values are substituted for those columns.

By understanding the distinctions between these types of joins, developers can effectively retrieve the desired data sets based on their specific requirements.
