In Mysql, joins are used to retrieve data from multiple tables. It is performed whenever two or more tables are joined.

There are three types of MySQL joins:-

  • MySQL INNER JOIN
    SELECT columns FROM table_1 INNER JOIN table_2 ON table_1.column = table_2.column;
  • MySQL LEFT JOIN
    SELECT columns FROM table_1 LEFT JOIN table_2 ON table_1.column = table_2.column;
  • MySQL RIGHT JOIN
    SELECT columns FROM table_1 RIGHT JOIN table_2 ON table_1.column = table_2.column;
