The SQL JOIN Clause

The JOIN clause is used to combine rows from two or more tables, based on a related column between them.

Here are the different types of JOINs in SQL:

(INNER) JOIN: Returns only rows that have matching values in both tables LEFT (OUTER) JOIN: Returns all rows from the left table, and only the matched rows from the right table RIGHT (OUTER) JOIN: Returns all rows from the right table, and only the matched rows from the left table FULL (OUTER) JOIN: Returns all rows when there is a match in either the left or right table
