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. |  |
