From the Schema Views Browser, the Set command from the Views menu enables you to set the selected schema view to the current active schema view.
The Set command is enabled only when you select a schema view that is not the current schema view.
To set a schema view as the current schema
In the Schema Views Browser window, select the schema view that you want to be the current schema view.
Select the Set command from the Views menu.
Double-click on a schema view in the Schema Views Browser to quickly set it to the current schema view.
An arrow is then displayed to the left of the selected schema view name in the Schema Views Browser window, indicating that it is the current schema view. That schema view remains the current schema view until another is set.
