Simply build a nice query with all the fields you need, and in include the
date field.
Now, add one more column to the query builder like:
MyQuarter:format([YourDateField],"q")
The above column will return the quarter. Now, fire up the report builder,
and simply make a "grouping" by the above quarter. Now, you can show all
data by quarter..and do all kinds of sums/ totals by quarter..
