Hinweise

Use the HostName property to have the Merge Agent override the value typically returned by the HOST_NAME function when this function is used to define a parameterized filter. For example, if you use the parameterized filter clause LoginID = HOST_NAME() to define horizontal filtering for an article, and if you set the HostName property to "adventure-works\david8" before calling the Synchronize method, the Merge Agent will synchronize data for the partition defined by "adventure-works\david8".

The case of the HostName property is ignored only when both the Publisher and the publication database are configured as case-insensitive.
