In SQL, multiple tables can be combined using JOIN operations. JOIN operations link rows from two or more tables based on their associated conditions.

Common types of JOIN operations include:

1. INNER JOIN: Returns the rows that satisfy the join condition from both tables. It only returns a result when there is a match in both tables.
2. LEFT JOIN: Returns all rows from the left table, and the rows from the right table that meet the join condition. If there are no matching rows in the right table, NULL values are returned.
3. RIGHT JOIN (or RIGHT OUTER JOIN): Returns all rows from the right table, as well as the rows from the left table that meet the join condition. If there are no matching rows in the left table, it returns NULL values.
4. FULL JOIN (or FULL OUTER JOIN): Returns all rows from both the left and right tables. If there is no match in a table, NULL values are returned.

These JOIN operations can be selected based on specific situations to meet the query requirements.
