I created a database model from MySQL to Visual Studio 2010. However, in the EntityObject's Create, for a table such as exam which has 9 columns, i only have two parameters (the key columns primary [id_exam], and foreign[user_id_exam]). Why could the rest be disappearing to what can i do about it?

Please help. I am totally stuck. :-(

[EdmEntityTypeAttribute(NamespaceName="examModel", Name="exam")]
    [Serializable()]
    [DataContractAttribute(IsReference=true)]
    public partial class exam : EntityObject
    {
        #region Factory Method
    
        /// <summary>
        /// Create a new exam object.
        /// </summary>
        /// <param name="id_exam">Initial value of the id_exam property.</param>
        /// <param name="user_id_user">Initial value of the user_id_user property.</param>
        public static exam Createexam(global::System.Int32 id_exam, global::System.Int32 user_id_user)
        {
            exam exam = new exam();
            exam.id_exam = id_exam;
            exam.user_id_user = user_id_user;
            return exam;
        }
