Question

I have the following data on a table
tbl Admission : Date and Time are two different fields and stored in dd/mm/yyyy format

AdmitDate          AdmitTime 
1/6/2012            00:00
3/6/2012            10:00
3/6/2012            19:00
4/6/2012            20:38
5/6/2012            21:00
7/6/2012            03:00

I would like to write a query to show all records between 3/6/2012 07:00:00 and 5/6/2012 06:59:59.

The query should also have the option of having ‘date’ input from user (only the date & time can be the fixed interval between 7 am first day to 6 59 am the second day) – for instance using PARAMETERS.
I use access 2003.
I tried several queries but am not able to perfect one – i do not get accurate results.
Somebody please help.

Thanks,

Regards,

If there was only one DATETIME column, the condition for the query would be easy to be constructed:

WHERE AdmitDateTime >= '2012-06-03 07:00' 
  AND AdmitDateTime <  '2012-06-05 07:00'

Since you can’t do that and because Access has its own Date and Time functions, I think this will work:

WHERE DateValue(AdmitDate) + AdmitTime 
         >= DateValue([InputDate]) + TimeValue('07:00')
  AND DateValue(AdmitDate) + AdmitTime 
         <  DateValue([InputDate]) + 2 + TimeValue('07:00')

The DateValue() calls are there to ensure that any time parts in the values passed by the user or in the AdmitDate column are chopped off and only the '07:00' and the AdmitTime are used.
