Introduction to Joins (SQL) - Combining Data (INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN)

In SQL, joins are used to combine data from two or more database tables, which have some relationship between them. An INNER JOIN returns matching records from both tables. A LEFT JOIN returns the left table and matches from the right table. A RIGHT JOIN returns the right table and matches from the left. A FULL OUTER JOIN returns all from both tables.
