Eingabedaten von Java zu SQL Datenbank

Question

Ich habe ein Schulprojekt, wo ich ein Register erstellen und GUI mit Netbeans anmelden und dann mit einer SQL-Datenbank verknüpfen muss. Ich erstelle die Datenbank und meine Login-Arbeit, aber ich kämpfe mit meiner Registrierung vielleicht kann mir jemand helfen. Das habe ich bisher gemacht. Sorry für den langen Code-Post, aber mein Fehler könnte irgendwo hier sein.

public class Register extends javax.swing.JFrame { 

Connection conn = null; 
Statement stat = null; 
ResultSet res = null; 

public Register() 
{ 
    initComponents(); 
} 

private Connection connect() { 
    // SQLite connection string 
    String url = "\"jdbc:derby://localhost:1527/MyDataBase\", \"LouwDataBase\", \"1234\""; 
    Connection conn = null; 
    try { 
     conn = DriverManager.getConnection(url); 
    } catch (SQLException e) { 
     System.out.println(e.getMessage()); 
    } 
    return conn; 
} 

public void insert(String Email, String Password, String Name, String Surname, String Address, String Cell) 
{ 
    String sql = "INSERT INTO Table1Test(Email, Password, Name, Surname, Address, Cell) VALUES(?,?,?,?,?,?)"; 

    try (Connection conn = this.connect(); 
     PreparedStatement pstmt = conn.prepareStatement(sql)) { 
     pstmt.setString(1, Email); 
     pstmt.setString(2, Password); 
     pstmt.setString(3, Name); 
     pstmt.setString(4, Surname); 
     pstmt.setString(5, Address); 
     pstmt.setString(6, Cell); 
     pstmt.executeUpdate(); 
    } 
    catch (SQLException e) 
    { 
     System.out.println(e.getMessage()); 
    } 
}

Answer 1

Ich denke, Ihr Problem in Ihrer URL ist, sollten Sie nicht Ihre URL wie ein String gesetzt, wie Sie tun:

String url = "\"jdbc:derby://localhost:1527/MyDataBase\", \"LouwDataBase\", \"1234\""; 

Sie haben die URL zu trennen, den Benutzernamen und Passwort wie folgt:

private Connection connect() { 
    // SQLite connection string 
    String url = "jdbc:derby://localhost:1527/MyDataBase"; 
    String username = "LouwDataBase"; 
    String password = "1234"; 
    Connection conn = null; 
    try { 
     conn = DriverManager.getConnection(url, username, password); 
    } catch (SQLException e) { 
     System.out.println(e.getMessage()); 
    } 
    return conn; 

}
