[santa]

hi I'v got a brain freeze and what i need to do is :

public static void connectDatabase(){

 Connection con = null;
 if(database.equals("")){
     JOptionPane.showMessageDialog(null, "Can't run without database!");
     System.exit(0);}

    try {
      Class.forName("com.mysql.jdbc.Driver").newInstance();
      con = DriverManager.getConnection("jdbc:mysql://",  // Using anonymous cause i feel like it =)
        "root", "test");


      if(!con.isClosed())
        System.out.println("Duude youre connected " +
          "trough TCP/IP...");

      stmt = con.createStatement();
      try{
      stmt.executeUpdate("USE " + database);
      System.out.println("Used old database!");
      old = true;
        }catch (Exception e){
           stmt.executeUpdate("CREATE DATABASE " + database);
           stmt.executeUpdate("USE " + database);
           System.out.println("Database created!");
        }
      if(!old){
      stmt.executeUpdate ("CREATE TABLE Borrowers ("
              + "cardnr INT,"
              + "name CHAR(60), "
              + "street CHAR(40), "
              + "zip INT,"
              + "town CHAR(50),"
              + "id INT NOT NULL AUTO_INCREMENT PRIMARY KEY)");

              stmt.executeUpdate ("CREATE TABLE GoodBooks ("
         + " ISBN long,"
        + " CopyNumber INT,"
        + " Title VARCHAR(60),"
        + " Author VARCHAR(30),"
        + " Publisher VARCHAR(50),"
        + " Year INT,"
        + " Statistics INT,"
        + " BorrowDate INT,"
        + " ReturnDate INT,"
        + " LibraryCardNumber INT,"
                      + "id INT NOT NULL AUTO_INCREMENT PRIMARY KEY)");
        }
      if(!old){
   for(int j = 0 ; j < Borrowers.borrow.length; j++){
                 stmt.executeUpdate("INSERT INTO Borrowers "
                         +"(cardnr, name, street, zip, town) "
                         + "VALUES "
                         + "('"+ Borrowers.borrow[j].LibraryCardNumber + "',"
                         + "'"+ Borrowers.borrow[j].Name + "',"
                         + "'"+ Borrowers.borrow[j].Street + "',"
                         + "'"+ Borrowers.borrow[j].ZipCode + "',"
                         + "'"+ Borrowers.borrow[j].Town + "')");
        }







for(int j = 0 ; j <Bookobjects.bookO.length ; j++){
                 stmt.executeUpdate("INSERT INTO goodbooks "
                         +"(ISBN, CopyNumber, Title, Author, Publisher, Year, Statistics,"
                         + " BorrowDate, ReturnDate, LibraryCardNumber) "
                         + "VALUES "
                         + "('"+ Bookobjects.bookO[j].ISBN + "',"
                         + "'"+ Bookobjects.bookO[j].CopyNumber + "',"
                         + "'"+ Bookobjects.bookO[j].Title + "',"
                         + "'"+ Bookobjects.bookO[j].Author + "',"
                         + "'"+ Bookobjects.bookO[j].Publisher + "',"
                         + "'"+ Bookobjects.bookO[j].Year + "',"
                         + "'"+ Bookobjects.bookO[j].Statistics + "',"
                         + "'"+ Bookobjects.bookO[j].BorrowDate + "',"
                         + "'"+ Bookobjects.bookO[j].ReturnDate + "',"
                         + "'"+ Bookobjects.bookO[j].LibraryCardNumber + "')");
        }
  


        }

    }catch(Exception e) {
      System.err.println("Fail: " + e.getMessage());
      System.out.println("Fail: " + e);
    }

if old is true ... update database
check in for Bookobjects.bookO.length and
Borrowers.borrow.length for new objects

Thank you for any help =P
