无法从套接字中读取更多数据
操作数据库的语句如下：

Java code

    public void insert(){
        init();
        String name = db.getName();
        String password = db.getPassword();
        String creator = db.getCreator();
        String description = db.getDescription();
        
        Connection conn = null;
        PreparedStatement stmt = null;
        
        try{
            conn = dataSource.getConnection();
            stmt = conn.prepareStatement("INSERT INTO DATABASES(DBNAME,DBPASSWORD,DBCREATOR,DBDESCRIPTION) VALUES(?,?,?,?)");
            stmt.setString(1, name);
            stmt.setString(2, password);
            stmt.setString(3, creator);
            stmt.setString(4, description);
        }catch(SQLException e){
            e.printStackTrace();
        }
        finally{
            if(stmt != null){
                try{
                    stmt.close();
                }catch(SQLException e){
                    e.printStackTrace();
                }
            }
            if(conn != null){
                try{
                    conn.close();
                }catch(SQLException e){
                    e.printStackTrace();
                }
            }
        }
        
    }
