You are looking for what is commonly referred to as a "pivot-table" or a
"cross-tab". Pivot-tables are a fairly sophisticated, non-normalized view of
a dataset, nd most commonly appear in spreadsheets and are used for
financial or statistical analysis.
These queries typically use an aggregate function (sum, min, max, etc....)
and a "group by" clause when generated from an SQL query...
There are lots of decent tutorials / samples out there (Google for "Pivot
Table SQL" and you'll see...)
