SQLITE_ERROR SQL錯誤或缺少數據庫（接近「VALUES」：語法錯誤）

Question

我有下面的代碼，它給了我這個錯誤。我需要在數據庫中顯示通過TCP連接傳輸的值。幫幫我？ 當我註釋Class.forName（「org.sqlite.JDBC」）和conexiune.setAutoCommit（false）之間的界限時;還有那些在IF中從String到conexiune.commit（）的工作很好，似乎客戶端和服務器之間的連接是可以的。

這是類服務器的方式運行：

public void run() { 
     while(true) 
     { 
      try 
      { 

       soc=server.accept(); 
       System.out.println("OK!"); 
       ObjectInputStream ois=new ObjectInputStream(soc.getInputStream()); 

       Class.forName("org.sqlite.JDBC"); 
       Connection conexiune=DriverManager.getConnection("jdbc:sqlite:BazaDeDate.db"); 
       System.out.println("Conexiunea la baza de date s-a realizat cu succes!"); 
       Statement comanda=(Statement) conexiune.createStatement(); 
       conexiune.setAutoCommit(false); 


       Object obj=ois.readObject(); 
       if(obj instanceof AvionPasageri) 
       { 
        AvionPasageri ap=(AvionPasageri)obj; 
        System.out.println(ap.toString()); 
        String s=""; 

        for(String sir : ap.getCnpPasageri()) 
        { 
         s+=sir; 
        } 
        ((java.sql.Statement) comanda).executeUpdate("INSERT INTO AvionPasageri(serie,tonaj,marca,capacitate,cnp VALUES(' " 
          +ap.getSerie()+"', '"+ap.getTonaj()+"', '"+ap.getMarca()+"', '"+ap.getCapacitate() 
          +"', '"+s+"')"); 
        System.out.println("Inserat!"); 
        conexiune.commit(); 

       } 
       else if(obj instanceof AvionCargo) 
       { 

        AvionCargo ac=(AvionCargo)obj; 
        System.out.println(ac.toString()); 
        String s=""; 

        for(String sir: ac.getSerieMarfuri()) 
        { 
         s+=sir; 
        } 
        ((java.sql.Statement) comanda).executeUpdate("INSERT INTO AvionPasageri(serie,tonaj,marca,capacitate,serii VALUES('" 
          +ac.getSerie()+"', '"+ac.getTonaj()+"', '"+ac.getMarca()+"', '"+ac.getCapacitate() 
          +"', '"+s+"')"); 
        System.out.println("Inserat!"); 
        conexiune.commit(); 
       } 

       conexiune.close(); 
       soc.close(); 


      } catch (IOException e) { 

       e.printStackTrace(); 
      } catch (ClassNotFoundException e) { 

       e.printStackTrace(); 
      } catch (SQLException e) { 
       e.printStackTrace(); 
      } 

     } 

我也有數據庫這裏的類：

public class CreareBazaDeDate 
{ 

    public static void main(String[] args) throws ClassNotFoundException, SQLException 
    { 
    Class.forName("org.sqlite.JDBC"); 

    Connection conexiune=DriverManager.getConnection("jdbc:sqlite:BazaDeDate.db"); 

    Statement comanda=(Statement) conexiune.createStatement(); 

    conexiune.setAutoCommit(false); 
    ((java.sql.Statement) comanda).executeUpdate("CREATE TABLE AvionPasageri(serie string, tonaj float, marca string, capacitate float, cnp string)"); 
    ((java.sql.Statement) comanda).executeUpdate("CREATE TABLE AvionCargo(serie string, tonaj float, marca string, capacitate float, marfa string)"); 

    conexiune.commit(); 
    conexiune.close(); 
    } 
} 

如果它可以幫助你，這是他的類服務器的第一部分，在運行之前（）：

public class Server implements Runnable 
{ 
    public ServerSocket server; 
    public Socket soc; 

    public static void main(String[] args) 
    { 
     Thread t=new Thread(new Server()); 
     t.start(); 
    } 

    public Server() 
    { 
     try 
     { 
      server=new ServerSocket(5200); 
     } 
     catch(IOException e) 
     { 
      e.printStackTrace(); 
     } 
    } 

你能幫我弄清楚有什麼問題嗎？

你需要有一個關閉右括號中

INSERT INTO AvionPasageri(serie,tonaj,marca,capacitate,cnp VALUES
