Argumenty

• [ @ publikacja = 'publikacja"
  Is the name of the publication to which the filtered data snapshot job is being added.publication is sysname, with no default.

• [ @ suser_sname=] 'suser_sname"
  Is the value used when creating a filtered data snapshot for a subscription that is filtered by the value of the SUSER_SNAME function at the Subscriber.suser_sname is sysname, with no default.suser_sname should be NULL if this function is not used to dynamically filter the publication.

• [ @ host_name=] 'host_name"
  Is the value used when creating a filtered data snapshot for a subscription that is filtered by the value of the HOST_NAME function at the Subscriber.host_name is sysname, with no default.host_name should be NULL if this function is not used to dynamically filter the publication.

• [ @ dynamic_snapshot_jobname=] 'dynamic_snapshot_jobname"
  Is the name of the filtered data snapshot job created.dynamic_snapshot_jobname is sysname, with default of NULL, and is an optional OUTPUT parameter.Jeśli określony, dynamic_snapshot_jobname musi być rozpoznawana unikatowy zadanie na dystrybutora.Jeżeli nie określono nazwy zadanie będą być automatycznie generowane i zwracane zestaw wyników, gdzie nazwa jest tworzona w następujący sposób:

  'dyn_' + <name of the standard snapshot job> + <GUID>
  

  Ostrzeżenie

  Podczas generowania nazwy zadanie dynamiczna migawka, może obciąć nazwę zadanie standardowego migawki.
