This aggregate function technique, including countless variations, can be very use when exporting data to other programs such as Excel. Or perhaps you want to send the revenue data to a website for display. Using this advanced union query technique allows you to avoid performing these aggregate function calculations either on the website, in a spreadsheet or in an Access report.

In some cases grouping can conflict in a report and can make the report difficult to program when there are many summary levels. Here are the results of the union query example:
