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.

Answer / itishree chhotray
View should be Schema binding,before creating index on view.
We can create Unique Clustered index on view after that we
can create non clustered index but we should have at least
one unique clustered index on view.
