by Dinesh Thakur Category: Servlet with MySql Database

The Function 'DATE_FORMAT' will use to see the format of the date.

First i make a table in database named 'dbase' within the reference of mySql(php myAdmin). Then i import all the required java packages from the java library. Then i made a class named 'MySqlDateFormat' which extends 'HttpServlet'. Then after i use service()Mehod which will get the request from the doGet()Method. Then i loaded all the require drivers for the database accessing. Here i declare the variables like 'connection' this variable will take over to create a link between a database and the java code. The other i declare 'resultSet' this will use to fetch the value from the columns and the rows from selected table. Then i declare the 'preparedStatement' this variable will execute the selected query like executeQuery() as (Select DATE_FORMAT(NOW(),'%W, %M %e, %Y')). I here use doGet()Method that will bring the output on the web browser.

On the web Browser i use 'HTML' tags that will represent the output in tabular form.
