I want to query the data within a period of time and then according to the interval

Select * from monitor thermometer where monitor thermometer. Time between'"+ Str (dtStart.Value) +" 'AND' "+ Str (dtEnd.Value) +" 'order by id

This is a query within a period of time. Now we need to add a time interval to query. I don't know what to say. I hope the master will answer.

Where dtStart.Value and dtEnd.Value are DTPicker1 controls

For example: for example, my query period is between 2007-1-5 19:03:31 and 2007-4-8 10:38:21. I think there is a data every few seconds and now I don't want him to take it all out. I need 5 minutes or how much time to get a data. If I have a record at 19:03:31 on 2007-1-5, the next record is directly 2007-1-5 19:08:31 (if not, it is closest to taking a record before and after this record). And at 2007-1-5 19:03:31, a lot of data will not be displayed at 2007-1-5 19:08:31. Thank you.

Try

Select * from Monitoring thermometer A where time between'"+ Str (dtStart.Value) +" 'AND' "+ Str (dtEnd.Value) +" And Not Exists (Select time From Monitoring thermometer Where DateDiff (mi, time, A. Time)
