Petterns for SQL Tables and Stored Proceduresdid not seem to have what I am looking for, but it would seem to me that it is a very commmon scenario that must have been covered. Basically, it is the problem of aggregating data for overviews. Assume the following: Table Services [SID][ServiceName][ServiceCategoryID][PID] [AmmountDue] Table Payer [PID][PayerCategory][PayerName] Table Payments [PayID][SID][Date][Amount][PID] ** Occasionally a third party might pay for someone else Table ServiceCategory [ServiceCategoryID][ServiceCategoryName] Table PayerCategory [PayerCategoryID][PayerCategoryName] Now, I want to get a summary of the data very quickly that breaks things down like: By ServiceCategory TotalAmountPaid TotalDue AmountDueFrom30DaysAgo ADF31-60DaysAgo adf61-90Days Ago Then break these down by PayerCategory This would seem like a common type of thing, and Ican think of ways to do this but that take a lot of time, if there are millions of rows, and I can imagine that triggers might be useful here to keep up to date, but I am unfamiliar with them. If you can give me any guidance on this it owuld be helpful. For extra points, what about being able to dynamically change the periods from say 0-30days to 0-15 days) Thanks a lot BB For starters, you need to post some ddl, sample data and expected results.
Not just a narrative. I can tell you this though - without dates in your services table or payments table to know when the service and payments took place, what you're looking for is impossible.

Thanks. The tables are internal ( I would not be allowed to post them) and a lot more complicated. For example the Payments Table has 31 fields in it, so I was trying to simplify. The Service does have a Date field. Sorry about the ommission. Really, I am looking for a general pattern for the problem of needing aggregate data from many, amny rows quickly, so I thought a narrative would be more useful. I will work on a model that is a little more simple, and for what is worth, I need the data in XML format from SQL 2000.
