Natural Right Join
In this program we are going to join the two table by
using the servlets and the result will be displayed in the browser. This join
will be natural right join.
To join the tables firstly it is important to make a
connection between the java class and the database. In our program we are using
the MySql database. To join the table in a natural right join manner, it is important to have those
tables in our database. First of all make a class named ServletNaturalRightJoiningTables.
The name of the class should be such that it becomes clear that what the program
is going to do. The logic of the program will be written inside the doGet()
method which takes two arguments HttpServletRequest and HttpServletResponse.
call the method getWriter() of the PrintWriter class, which is
responsible for writing the contents on the browser. Our priority is to join the
two tables so pass a query in prepareStatement() method which will return
the PreparedStatement object.
The result will be displayed to you by the object of
the PrintWriter class.
