6. Using JoinDefs in QBF : Test JoinDefs
Share this page                  
Test JoinDefs
QBF provides a convenient way to test your JoinDef while you are still defining it. At the JoinDef Definition frame, choose the Go operation. QBF builds a form for the JoinDef and automatically goes into the query execution phase. In query execution, you can append, retrieve, or update data in the tables used in your JoinDef. These operations are described later in this chapter.
When you exit query execution after testing a JoinDef, QBF returns you to the JoinDef Definition frame so that you can view or modify your JoinDef entries. After making changes, you can easily switch to query execution phase by clicking Go again.
