Namespace: Microsoft.SqlServer.Replication
Assembly: Microsoft.SqlServer.Replication (in microsoft.sqlserver.replication.dll)

Syntax

'Declaration
Public Property DynamicFilterHostName As String

public string DynamicFilterHostName { get; set; }

public:
virtual property String^ DynamicFilterHostName {
    String^ get () sealed;
    void set (String^ value) sealed;
}

/** @property */
public final String get_DynamicFilterHostName ()

/** @property */
public final void set_DynamicFilterHostName (String value)

public final function get DynamicFilterHostName () : String

public final function set DynamicFilterHostName (value : String)

Property Value

A String value used for filtering.

Remarks

The value specified for DynamicFilterHostName is used when generating the partitioned snapshot for a subscription defined based-on a parameterized row filter that uses the HOST_NAME function. For example, if the subset filter clause LoginID = HOST_NAME() is specified for an article, and you set the DynamicFilterHostName property to "adventure-works\garrett1" before calling the Merge Agent, only rows having "adventure-works\garrett1" in the login_id column will be replicated.

The DynamicFilterHostName property is only supported for merge publications.

You should not specify a value for DynamicFilterHostName when specifying a value for DynamicFilterLogin.

Example

// Set the Publisher, publication database, and publication names.
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks";
string publisherName = publisherInstance;
string distributorName = publisherInstance;

SnapshotGenerationAgent agent;

try
{
    // Set the required properties for Snapshot Agent.
    agent = new SnapshotGenerationAgent();
    agent.Distributor = distributorName;
    agent.DistributorSecurityMode = SecurityMode.Integrated;
    agent.Publisher = publisherName;
    agent.PublisherSecurityMode = SecurityMode.Integrated;
    agent.Publication = publicationName;
    agent.PublisherDatabase = publicationDbName;
    agent.ReplicationType = ReplicationType.Merge;

    // Specify the partition information to generate a 
    // filtered snapshot based on Hostname.
    agent.DynamicFilterHostName = hostname;

    // Start the agent synchronously.
    agent.GenerateSnapshot();
}
catch (Exception ex)
{
    // Implement custom application error handling here.
    throw new ApplicationException(String.Format(
        "A snapshot could not be generated for the {0} publication."
        , publicationName), ex);
}

' Set the Publisher, publication database, and publication names.
Dim publicationName As String = "AdvWorksSalesOrdersMerge"
Dim publicationDbName As String = "AdventureWorks"
Dim publisherName As String = publisherInstance
Dim distributorName As String = publisherInstance

Dim agent As SnapshotGenerationAgent

Try
    ' Set the required properties for Snapshot Agent.
    agent = New SnapshotGenerationAgent()
    agent.Distributor = distributorName
    agent.DistributorSecurityMode = SecurityMode.Integrated
    agent.Publisher = publisherName
    agent.PublisherSecurityMode = SecurityMode.Integrated
    agent.Publication = publicationName
    agent.PublisherDatabase = publicationDbName
    agent.ReplicationType = ReplicationType.Merge

    ' Specify the partition information to generate a 
    ' filtered snapshot based on Hostname.
    agent.DynamicFilterHostName = hostname

    ' Start the agent synchronously.
    agent.GenerateSnapshot()
Catch ex As Exception
    ' Implement custom application error handling here.
    Throw New ApplicationException(String.Format( _
     "A snapshot could not be generated for the {0} publication." _
     , publicationName), ex)
End Try
