Comentários

A PublicationAttributes enumeração dá suporte à opção FlagsAttribute , que permite uma combinação bit a bit de valores de enumeração. Consulte sp_addpublication (Transact-SQL) e sp_addmergepublication (Transact-SQL) para obter informações sobre valores de atributo padrão para publicações transacionais ou de instantâneo e publicações de mesclagem, respectivamente.

A Attributes propriedade só pode ser recuperada por membros da função de sysadmin servidor fixa no Publicador, por membros da função de banco de db_owner dados fixa no banco de dados de publicação ou por usuários na PAL (lista de acesso à publicação).

A Attributes propriedade só pode ser definida por membros da sysadmin função de servidor fixa no Publicador ou por membros da db_owner função de banco de dados fixa no banco de dados de publicação. Os usuários no PAL podem definir a Attributes propriedade de uma publicação existente.

Recuperar a Attributes propriedade é equivalente à execução de sp_helppublication ou sp_helpmergepublication.

Definir a Attributes propriedade é equivalente à execução de sp_addpublication e sp_changepublication ou sp_addmergepublication e sp_changemergepublication.
