Join tables in
the specific database
In this section, we are going to consider how to join two or more tables
in a specific database. For this you need to have two or more table in the
database. If two or more tables are available in the database then Join
operation is performed otherwise not.

with the NATURAL LEFT JOIN operation
This section describes the NATURAL LEFT JOIN operation and
how to retrieve data through it. In this operation we are going to retrieve
data according to match the field name of another tables.
Join tables
with the NATURAL RIGHT JOIN operation
