[Ms.Ranjan]

Hi all

this thread is for beginners like me..just want to share the code which i tried out..

import java.io.*;
import java.sql.*;

class Sample
{
public static void main(String ds[])
{
Connection con=null;
Statement st=null;
ResultSet rs=null;
String FirstName="";
try
{

Class.forName("com.mysql.jdbc.Driver").newInstance ();

con=DriverManager.getConnection("jdbc:mysql://localhost:3306/yourdatabasename?","root","password?");
st=con.createStatement() ;
rs=st.executeQuery("SELECT fieldname? FROM yourTablename?") ;
while(rs.next())
{
FirstName=rs.getString(1);
System.out.println(fieldname);
}

}
catch(Exception eer)
{
System.out.println(eer.toString());
}
}
}

if anything is wrong please correct me...

The "FirstName" in the code is my field name you can give yours..

You need to close your resources in a finally block. At the moment you are not closing anything, and that is very bad.
