IMPLEMENTATION OF JAVA DATABASE CONNECTIVITY (JDBC)

AIM:

To connect the database using jdbc connectivity in java.

ALGORITHM:

Step 1: Start the program.

Step2 : Write the source code for connectivity.

Step 3: Using MS-Access, save the database.

Step 4: connect the database using ODBC Source connection.

Step 5: Add the database name in ODBC data source administrator.

Step 6: Add the table name to connection.

Step 7: Compile the program and execute it.

Step 8:Stop the program.



PROGRAM:

import java.sql.*;

import java.io.*;

public class jdbcdemo

{

public static void main(String args[])

{

Connection c= null;

try

{

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

c=DriverManager.getConnection("jdbc:odbc:jdbcdemodb");

Statement stmt=c.createStatement();

ResultSet rs=stmt.executeQuery("select * from Employee");

System.out.println("name and password are");

while(rs.next())

{

System.out.println(rs.getString(1)+"\t"+rs.getInt(2)+"\t"+rs.getDouble(3));

}

c.close();

}

catch(SQLException e1)

{

e1.printStackTrace();

}

catch(Exception e)

Step4:Using various HTML tags and attribute,we design the web page.

Step5:Using various XML attribute list and entity list to retrieve the information of student.

Step6:Using processing instructions which we required to describe the data.

Step7:Using “note.xml”as xmlid to connect with html file.Execute the program.

Step8:Stop the program.
