![]() | Returns all records from the left table, and the matched records from the right table |
![]() | Returns all records from the right table, and the matched records from the left table |

Inner JOIN

SELECT columns
FROM table1
INNER JOIN table2
ON table1.column = table2.column;


Left Outer JOIN

SELECT columns
FROM table1
LEFT [OUTER] JOIN table2
ON table1.column = table2.column;

Right Outer JOIN

SELECT columns
FROM table1
RIGHT [OUTER] JOIN table2
ON table1.column = table2.column;

Cross JOIN

SELECT columns
FROM table_1
CROSS JOIN table_2;
Unlike the INNER JOIN
, LEFT JOIN
, and RIGHT JOIN
, the cross join clause does not have a join condition.
