How to use another table fields as a criteria for MS Access

Question

This is the MS Access related query.

I have a table with three columns: FName, FValue and VDate in MS Access.(The actual table is quite big bu

Answer 1

Make a new tables "quarters" with fields for Yr, Qtr, Start and End. Start and End are date/time fields:

Quarters
Yr      Qtr Start       End

2014    1   1/1/2014    3/31/2014
2014    2   4/1/2014    6/30/2014
2014    3   7/1/2014    10/31/2014

Then use this query:

SELECT Quarters.Yr, Quarters.Qtr, Table.FName, Min(Table.FValue) AS FValue
FROM [Table], Quarters
WHERE (((Table.CDate)>=[start] And (Table.CDate)<=[end]))
GROUP BY Quarters.Yr, Quarters.Qtr, Table.FName;

Note - there is no join between the two tables in the query.
