PHP SQL Right Join

This Example illustrates how to use right join clause in the sql query.

JOIN is used to query data from two or more tables. The right join is used in case of need to return all rows from the right table, even if the left table doesn't have any match. In this example right join is used to join the two table data according to the emp_id field of the "message" table. We are using "emp","message" tables in the example. We will find the name from emp table and messages from message table where emp_id in both tables are equal. The fetched result is displayed on the browser as below and the complete source code is available below for download or copy the code as per your need.

Table: emp

Table: message
