An index cannot be defined on a view. Because view is
virtual table, which consists of a subset of columns from
one more tables.

The Restrictions imposed on views are as follows:
1. A view can be created only in the current database.
2. A view can be created only if there is a SELECT
permission on its base table
3. A Trigger or an Index cannot be defined on a view.
4. A view cannot be derive its data from temporary tables.
5. The CREATE VIEW statement cannot be combined with other
SQL statements in a single batch.
