EnumMergeAgentSessions2 Method
Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The EnumMergeAgentSessions2method returns a QueryResults object that enumerates execution status data for the merge replication agent specified.
Syntax

Parts
object
Expression that evaluates to an object in the Applies To list.AgentName

The EnumMergeAgentSessions2 method differs from the EnumMergeAgentSessions method by including the lEstimatedNumRecords parameter, which allows an application to pass an estimated number of QueryResults rows. This allows the application to avoid the performance overhead associated with repeatedly allocating and freeing memory.
