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
