I am in the process of trying to find out whether a date range falls between another date range and need help.

I have a table that lists the following:

Service Date End Date + 30 days - 30 days

06/04/04 9/2/04 7/4/04 5/4/04
9/25/04 12/24/04 7/4/04 5/4/04
9/29/03 10/29/06 2/2/04 12/4/03

And so on. I wanted to run a query to find out whether the range of (Service Date And End Date) fell within the range of (+30 days And - 30 Days).

Can someone please help.

Thanks

This will work. I chose to call the columns

"Start" "End" "Minus30" and "Plus30"

1. Make a query in design view
2. Save it
3. Double click each of the four fields to a column in the query design grid to add them to the query.
4. In the 'field' cell of the next column, type the following expression:

Expr1: IIf(([Start]>=[Minus30]) And ([End]<=[Plus30]),"Within the range","Not within the range")

Note the unusual spelling of "If" - it has two i's then one f.

Second term is what's returned if the expression is true (I chose a text) and the third term is what's returned if the expression is false i.e. if the service dates are not within the other range.

Unless I'm missing something, you should be able to just use the expression:

([Start] between [Minus30] and [Plus30]) and ([End] between [Minus30] and [Plus30])
