使用'CLF'+CAST(YearOf(ServerTime())as char) + CAST(MonthOf(ServerTime()) as char) + CAST(DayOf(ServerTime()) as char) + CAST(HourOf(ServerTime())as char) + CAST(MinuteOf(ServerTime()) as char) + CAST(SecondOf(ServerTime()) as char) + CAST(MilliSecondOf(ServerTime()) as char)公式进行自动填充,系统总默认填充一串GUID码,升级前无此现象
