4TOPS Query Tree Editor is an add-in for MS Access for query development. Create queries using templates. Edit and run queries from a tree dialog. The Query Tree dialog displays the dependency tree of the selected query (Uses / Used By). The buttons on the dialogs support a natural way of working with queries, smoothly switching from the tree overview to query editing to saving different versions or running them to evaluate the results. Double-click on a query opens the query datasheet. Press the Edit button to make required changes using the Query Editor. The Print button writes the tree to the Debug Window. Use it to compare query dependency trees or to paste it into your documentation. Double-click on multiple queries to compare results. This will help you diagnose in case queries don't return the results you expected.
