FORMULAS FOR JOINS 💢 INNER JOIN = Inner join will only fetch the matching record from the opposite table you mentioned. LEFT JOIN = Inner join + fetch any additional records from the left table which is not present in the right table. RIGHT JOIN = Inner join + fetch any additional records from right table which is not present in left table. FULL JOIN = Inner join + fetch any additional records from left table which is not present in right table + fetch any additional records from right table which is not present in left table.
