import java.io.*;
public class Index{
public static void main(String[] args)throws IOException{
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
String userId = "";
System.out.println("Welcome to New World Inc.");
System.out.println("1. Create new user");
int choice = 0;
do{
System.out.print("Please select an option: ");
try{
choice = Integer.parseInt(input.readLine());
catch(NumberFormatException e){
//e.printStackTrace();
choice = 0;
}while(choice<1 || choice>3);
if(choice==1){
Account acc = new Account();
do{
System.out.print("Enter user name: ");
try{
userId = input.readLine();
acc.setUserId(userId);
catch(Exception e){
e.printStackTrace();
}while(userId.equals(""));
import java.sql.*;
public class Account{
DBC dbc;
public Account(){
dbc = new DBC();
dbc.setUp("database");
public void setUserId(String userId){
int status = dbc.updateRequest("INSERT INTO Account VALUES('" + userId + "','','')");
dbc.updateRequest("INSERT INTO Account VALUES('" + userId + "','','')");
//<===== i wonder why i need to write an additional updateRequest then i am able to insert a new record into my database....
//its so weird. and everytime i take away this additional method, i cannot add a new record into my database
import java.sql.*;
public class DBC{
private Connection con;
public void setUp(String dsn){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
catch(Exception e){
System.out.println("Load driver error");
try{
String s = "jdbc:odbc:" + dsn;
con = DriverManager.getConnection(s, "", "");
catch(Exception e){
e.printStackTrace();
public int updateRequest(String dbQuery){
int count=0;
try{
Statement stmt = con.createStatement();
stmt.executeUpdate(dbQuery);
count = 1;
catch(Exception e){
count = -1;
return count;
}

DrClap, are you able to give me a solution as to how can i commit the update or close the connection ? however i notice something you might have "mistakened"
its not that i can't create a new record into my database... when i only put a single executeUpdate(), the new record is not created, but when i put 2 lines of executeUpdate() then the new record is reflected in the database...
hope you may give me some code samples to clarify my doubts to this issue.
thanks in advance
