Delete JoinDefs
You can delete a JoinDef with the JoinDefs Catalog frame. Place the cursor on the name of the JoinDef you want to erase and choose the Destroy operation. QBF prompts you for confirmation:
Do you wish to destroy JoinDef 'name'?
Type y (yes) to permanently delete the JoinDef. Type n (no) if you decide not to delete the JoinDef.
You can also delete a JoinDef on the command line, using the
delobj command (see
delobj Command–Delete Objects from Database).
