I have a following question regarding crosstabs in Access: How do I create a subtotal columns?
What I want to see as a result of the query is this:
Nov 2010 Dec 2010 2010 Total Jan 2011 Feb 2011
Row1 2 4 17 3 2
Row2 8 6 35 7 5
How do I create these subtotals for the year? (It's ok, if the year data will be in the end, after all months) The problem is that I need to do this without hardcoding each year, the query should work with any dataset
Thanks in advance!

Say we have raw [SalesData]
SalesYear SalesMonth Region SalesTotal
--------- ---------- ------ ----------
2010 11 East 45
2010 11 West 58
2010 12 East 55
2010 12 West 63
2011 1 East 51
2011 1 West 54
2011 2 East 55
2011 2 West 61
We can create a [SalesTotals] query to combine the monthly sales totals with the yearly totals...
SELECT SalesYear & "-" & Format(SalesMonth, "00") AS SalesPeriod, Region, SalesTotal FROM SalesData
UNION ALL
SELECT SalesYear & "-Total", Region, SUM(SalesTotal) FROM SalesData GROUP BY SalesYear, Region;
...which produces
SalesPeriod Region SalesTotal
----------- ------ ----------
2010-11 East 45
2010-11 West 58
2010-12 East 55
2010-12 West 63
2011-01 East 51
2011-01 West 54
2011-02 East 55
2011-02 West 61
2010-Total East 100
2010-Total West 121
2011-Total East 106
2011-Total West 115
Then we can do our crosstab query on the [SalesTotals] query...
TRANSFORM Sum(SalesTotals.[SalesTotal]) AS SumOfSalesTotal
SELECT SalesTotals.[Region]
FROM SalesTotals
GROUP BY SalesTotals.[Region]
PIVOT SalesTotals.[SalesPeriod];
...which produces
Region 2010-11 2010-12 2010-Total 2011-01 2011-02 2011-Total
------ ------- ------- ---------- ------- ------- ----------
East 45 55 100 51 55 106
West 58 63 121 54 61 115
