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
