To run SQL queries that combine data from multiple tables, you typically use INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN. An INNER JOIN returns only the rows with matching values in both tables, while a LEFT JOIN returns all rows from the left table and matched rows from the right. A RIGHT JOIN does the opposite, and a FULL OUTER JOIN returns all rows from both tables, filling in gaps with NULLs where there are no matches.
