Notes

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

Tout membre statique public (Partagé dans Microsoft Visual Basic) de ce type est sûr dans le cadre des opérations à plusieurs threads. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.

Exemples

Création, modification et suppression d'index

Sécurité des threads

Tous les membres publics static (Shared dans Visual Basic) de ce type sont thread-safe. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.
