We've seen how you can create simple,
single-query reports with the Report
Wizard. For most reports, one query is
sufficient. However, some reports
require multiple queries.
For example, a group report
uses two queries that are joined based
on the primary and foreign keys of the
underlying tables, as shown by the Query Builder linked-queries graphic, on the right side of this page.
For each record in
the master group, related records in the
detail group are retrieved.
