Osservazioni

To get Index object properties, users can be a member of the public fixed server role.

To set Index object properties, create or drop an index, update statistics on an index, or rebuild, reorganize, or re-create an index, users must have one of the following:

• ALTER permission on the parent table or view

• Membership of the db_owner or the db_ddladmin fixed database roles

• Membership of the sysadmin fixed server role

Thread Safety

Tutti i membri statici pubblici (Shared in Microsoft Visual Basic) di questo tipo sono sicuri per le operazioni a thread multipli. Non è invece garantita la sicurezza dei membri dell'istanza.
