You can modify an existing relational view in the current schema. When you modify a relational view, you cannot change the relational view name.
To change a relational view
Select the Change command from the Relational menu.
The Relational View Wizard is then displayed. For details about the Relational View Wizard steps, see "Adding a Relational View", earlier in this chapter.
When you are changing an existing relational view, the text box in the first dialog of the Relational View Wizard displays the name of your relational view.
As you cannot change the name of an existing relational view, the text box is disabled.
