Osservazioni

The PublicationAttributes enumeration supports the FlagsAttribute option, which allows a bitwise combination of enumeration values. See sp_addpublication (Transact-SQL) and sp_addmergepublication (Transact-SQL) for information about default attribute values for transactional or snapshot publications and merge publications respectively.

The Attributes property can only be retrieved by members of the sysadmin fixed server role at the Publisher, by members of the db_owner fixed database role on the publication database, or by users in the publication access list (PAL).

The Attributes property can only be set by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database. Users in the PAL can set the Attributes property of an existing publication.

Retrieving the Attributes property is equivalent to executing sp_helppublication or sp_helpmergepublication.

Setting the Attributes property is equivalent to executing sp_addpublication and sp_changepublication or sp_addmergepublication and sp_changemergepublication.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
