Date in a Query

Dear Experts,

I need to be able to create a field in a query which returns the first and last dates in a range ([DateAndTime]).  So something like "'First date' to 'Last date'"

This needs to be added into a query which then forms the dataset for a count query (the count is based on [DateAndTime]). I have tried playing around with the Expression Builder, but I’m not getting very far
The query I have is below ... Can anybody help?

SELECT FFUsers_Contact_Information.DateAndTime, FFUsers_ConsultantDefs.Description, FFUsers_ConsultantDefs.entry AS FFID
FROM FFUsers_UsersPreferences INNER JOIN (FFUsers_Contact_Information INNER JOIN FFUsers_ConsultantDefs ON FFUsers_Contact_Information.createby = FFUsers_ConsultantDefs.entry) ON FFUsers_UsersPreferences.user_log_in = FFUsers_ConsultantDefs.entry
GROUP BY FFUsers_Contact_Information.DateAndTime, FFUsers_ConsultantDefs.Description, FFUsers_ConsultantDefs.entry, FFUsers_UsersPreferences.is_current
HAVING (((FFUsers_UsersPreferences.is_current)=1)); 

Open in new window


Many thanks

I'm not sure I understand what you are asking for.

Are you saying you want to know the values of the oldest and newest datetimes in the field DateAndTime?  

If so then it seems that you need a separate query..

Select min(Dateandtime) as FirstDate, max(dateandtime) as LastDate
from FFUsers_Contact_Information

... the query is grouping by DateAndTime so the max and min values will just be the same as the grouping value.
