Project on Netbeans Using MySql Workbench as Database. Insert Data into Database is Working but cannot retrieve the same. It throws error "No Data Found!". Checked the connection and its ok. Below are the codes that i used to establish connection. Please Help !!

try
    {
        Class.forName("java.sql.Driver");
        cn = DriverManager.getConnection("jdbc:mysql://localhost:3306/avinash?useSSL=false","root","password");
    }
            catch(ClassNotFoundException e)  
            {
        System.err.println("Failed to load driver");
        e.printStackTrace();
    }
    catch(SQLException e)
            {
        System.err.println("Unable to connect");
        e.printStackTrace();
    }

Answer 1

add st=cn.createStatement(); in your connection after line below.

cn = DriverManager.getConnection("jdbc:mysql://localhost:3306/avinash?useSSL=false","root","password");

i don't get in what you need to do.

but i think in beginning would be

try {
   nm = nametxt.getText();
if(nm != '') {
   rs = st.executeQuery("SELECT * FROM chsl_db WHERE name ='" + nm + "'");
while (rs.next()) {
   titletxt.setText(rs.getString(1));
   nametxt.setText(rs.getString(2));
   flatnum.setText(rs.getString(3));
   areatxt.setText(rs.getString(4));
   emailtxt.setText(rs.getString(5));
   deletebutton.setEnabled(true);
}
 st.close();
 }
 else {
JOptionPane.showMessageDialog(null,"No Data Found!","Security Warning",JOptionPane.WARNING_MESSAGE);
 }
}

its been a while i'm not using Netbeans. So tell me if i was wrong.
