                    _Instance = new TempTable();
                return _Instance;
            }
        }
        private static TempTable _Instance = null;

        public DataTable GetData(string SQL)
        {
            return DBWR.Instance.ReadData(SQL);
        }

        {
            return DBWR.Instance.GetSingleValue(SQL);
        }
