You can test a new query in Design view. Just click the Run button
on the Query Design toolbar. This will switch you to the results view.
If you don't see the results you want, click the Design button
to return to Design view for more tweaks.
To run a query, all you need to do is to open it by double-clicking it in the list of queries, which appears when you click Queries under Objects in the Database window.
To better display your query results, you may want to create a form; to better print your query results, you can create a report. For more information, see the courses "Forms follow function" and "Reports I: Show off your data."
