Jsp + My Sql

JSP to create usable apps. A fun way + MySQL

THE BASICS • What is JSP? • What is JDBC? • What is ODBC?

What Exactly is JDBC? • JDBC is an API for the Java programming language that defines how a client may access a database. It provides methods for querying and updating data in a database. JDBC is oriented towards relational databases. Servlet JDBC ODBC DB

How do we do that???

Loading the JDBC Driver • We should have the Driver!!! • MySQL Connector/J - version 2 used for this tutorial Download Link : http://dev.mysql.com/downloads/connector/j/ • Copy it to the “lib” folder in the server.

Loading the JDBC Driver • To load the driver you only need to load the appropriate class. • Syntax : Class.forName(“fully qualified class name”) • For MySQL : Class.forName(“com.mysql.jdbc.driver”)

Defining the connection URL • Driver is ready to go..But where??? • Define a connection URL which specifies the SERVER & the Database needed • “jdbc:mysql://localhost:3306/db_name”

Establishing the connection • The actual network connection!! • Connection conn=DriverManager.getConnection(“Connection URL”,”user”,”pass”);

Creating the statement Object • Statement stmt = conn.createStatement(); • Statement Object sends queries and commands to the database.

HOW EXACTLY DOES ALL THIS WORK??? LIVE DEMO
