Comentários

Use a HostName propriedade para que o Agente de Mesclagem substitua o valor normalmente retornado pela função HOST_NAME quando essa função é usada para definir um filtro parametrizado. Por exemplo, se você usar a cláusula LoginID = HOST_NAME() de filtro parametrizada para definir a filtragem horizontal de um artigo e se você definir a HostName propriedade para "adventure-works\david8" antes de chamar o Synchronize método, o Agente de Mesclagem sincronizará os dados para a partição definida por "adventure-works\david8".

O caso da HostName propriedade é ignorado somente quando o Publicador e o banco de dados de publicação são configurados como diferenciais de maiúsculas de minúsculas.
