Question

I\'ve connected to a MySQL database, which contains four fields (the first of which being an ID, the latter ones each containing varchar strings).

I am trying to get the

Answer 1

Here is what I just did right now:

import java.sql.*;
import java.util.logging.Level;
import java.util.logging.Logger;

import com.sun.javafx.runtime.VersionInfo;  

public class ConnectToMySql {
public static ConnectBean dataBean = new ConnectBean();

public static void main(String args[]) {
    getData();
    }



public static void getData () {

    try {
        Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mynewpage", 
 "root", "root");
        
 // here mynewpage is database name, root is username and password
    
Statement stmt = con.createStatement();
        System.out.println("stmt  " + stmt);
        ResultSet rs = stmt.executeQuery("select * from carsData");
        System.out.println("rs  " + rs);
        int count = 1;
        while (rs.next()) {
            String vehicleType = rs.getString("VHCL_TYPE");
            System.out.println(count  +": " + vehicleType);
            count++;

        }

        con.close();
    } catch (Exception e) {
        Logger lgr = Logger.getLogger(VersionInfo.class.getName());
        lgr.log(Level.SEVERE, e.getMessage(), e);

        System.out.println(e.getMessage());
    }
    
    
}

}

The Above code will get you the first column of the table you have.

This is the table which you might need to create in your MySQL database

CREATE TABLE
carsData
(
    VHCL_TYPE CHARACTER(10) NOT NULL,
);
