This SELECT statement can reference more than one table/view. Appropriate permissions are required. cannot include a COMPUTE or ORDER BY clause (unless SELECT TOP..) CHECK OPTION Enforce the criteria set with select_statement even when modifying the data. This only affects the view not the underlying table. ENCRYPTION Encrypts the text of the CREATE VIEW statement. SCHEMABINDING Bind the view to the schema of the underlying table or tables. VIEW_METADATA Return metadata information about the view to client APIs this allows updatable client-side cursors to address the view.

Using ALTER VIEW will retain all the permission settings.
