I do not believe that a single "query" will give you what you want here.  YOU could have 3
seperate queries:
1 for customer detail by state.
1 for state total 
1 for grand total

However, if you use a reporting tool like crystal or others, they have the ability to generate
summaries exactly as you are referring to here.  you would only need to pass it the query on total
per customer.  The reporting utility has a groupby feature where it would group the customers by
state for your.  In the group by summary it would automaticly display state total.  Then if the
report footer you could add a grand total summary for all of the records you passed to the report.

The following link show some of the reporting programs that you can use.
