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

object
.EnumMergeAgentSessions2(
AgentName
,
SessionType
, 
SessionDuration
,
lEstimatedNumRecords
)
as 
QueryResults

Parts

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

  • AgentName
    String that identifies a merge replication agent by name.

  • SessionType
    Long integer that indicates session type as described in Settings.

  • SessionDuration
    Long integer that specifies a number of hours. Restricts result set membership to those sessions launched within the number of hours specified. Use 0 to specify no restriction on agent session start time.

  • lEstimatedNumRecords
    Long integer that specifies the estimated number of QueryResults rows to return.

Prototype (C/C++)

HRESULT EnumMergeAgentSessions2(
SQLDMO_LPCSTR AgentName,
SQLDMO_SESSION_TYPE SessionType,
long SessionDuration,
long lEstimatedNumRecords,
LPSQLDMOQUERYRESULTS* ppResults);

Settings

Set SessionType using these values.

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.
