Filter one data set on the resultes of another query

$

I have one data set that has a numeric field: X -

There is another query on a different data set the returns a From field and a To field - I want to filter the first data set returning only records X that fall between From and To in the 2nd query.

 

The query on the 2nd data set is in Access for now.  The first data set is in the ODBC. 

 

The First data set is millions of records and we are looking for only a few thousand. What is the best method for returning the filtered data so it works quickly?
