EnumSnapshotAgentSessionDetails2 Method

この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

The EnumSnapshotAgentSessionDetails2 method returns a QueryResults object that enumerates detail information for a specified Snapshot Agent session.

構文

object.EnumSnapshotAgentSessionDetails2(AgentName ,SessionID,lEstimatedNumRecords)as QueryResults

Parts

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

  • AgentName
    String that identifies a Snapshot Agent by name.

  • SessionID
    String that identifies a session. The SessionID value is specified using the first 21 characters of the time column value in the QueryResults result set returned by the EnumSnapshotAgentSessions method.

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

Prototype (C/C++)

HRESULT EnumSnapshotAgentSessionDetails2(
SQLDMO_LPCSTR AgentName,
SQLDMO_LPCSTR SessionID,
long lEstimatedNumRecords,
LPSQLDMOQUERYRESULTS* ppResults);

Returns

A QueryResults object that contains one result set defined by these columns.

The EnumSnapshotAgentSessionDetails2 method differs from the EnumSnapshotAgentSessionDetails 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.

To increase the accuracy of the estimated number of QueryResults rows, an application can pass the value of the action_count column returned by the EnumSnapshotAgentSessions or EnumSnapshotAgentSessions2 method to the lEstimatedNumRecords parameter.
