示例1: GetFirstAndLastEpoch

        public void GetFirstAndLastEpoch()
        {
            using (var db = new OrmLiteConnectionFactory(GetSQLiteConnectionString(), SqliteDialect.Provider).OpenDbConnection())
            {
                using (var cmd = db.CreateCommand())
                {
                    cmd.CommandText = "SELECT dataTimestamp FROM data ORDER BY dataTimestamp limit 1";
                    using (var rdr = cmd.ExecuteReader())
                    {
                        while (rdr.Read())

                            long firstEpoch = (long) rdr[0];
                            FirstEpoch = new DateTime(firstEpoch);
                        }
                    }

                    cmd.CommandText = string.Format("SELECT dataTimestamp FROM data WHERE dataTimeStamp > {0} ORDER BY dataTimestamp limit 1", FirstEpoch.Ticks);
                    using (var rdr = cmd.ExecuteReader())
                    {
                        while (rdr.Read())
                        {
                            var secondEpoch = new DateTime((long)rdr[0]);
                            EpochLengthInSeconds = (int) secondEpoch.Subtract(FirstEpoch).TotalSeconds;
                        }
                    }

                    cmd.CommandText = "SELECT dataTimestamp FROM data ORDER BY dataTimestamp DESC limit 1";
                    using (var rdr = cmd.ExecuteReader())
                    {
                        while (rdr.Read())
                        {
                            long lastEpoch = (long) rdr[0];
                            LastEpoch = new DateTime(lastEpoch);
                        }
                    }

                    EpochCount = db.Scalar<long>(db.From<AgdTableTimestampAxis1>().Select(Sql.Count("*")));
                }
            }
        }
