Question

I have a query pulling the last six months of data from a table which has a column, UseDates (so as of today in June, this table has dates for December 2011 through May 2012).

I wish to include a “rank” column that associates a 1 to all December dates, 2 to all January dates, etc — up to 6 for the dates corresponding one month prior. If I were to open up this query a month from now, the 1 would then be associated with January, etc.

I hope this makes sense!

Example, if I ran the query right now

UseDate        Rank
12/31/2011     1
1/12/2012      2
...
5/23/2012      6

Example, if I ran the query in August:

UseDate        Rank
2/16/2012      1
3/17/2012      2
...
7/21/2012      6

Example, if I ran the query in March:

UseDate        Rank
9/16/2011      1
10/17/2011     2
...
2/24/2012      6

Answer 1

SELECT
    UseDates,
    DateDiff("m", Date(), UseDates) + 7 AS [Rank]
FROM YourTable;
