EnumLogReaderAgentSessionDetails2 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 EnumLogReaderAgentSessionDetails2 method returns a QueryResults object that enumerates detail information for a specified Log Reader Agent session.
構文

SQLDMO_LPCSTR AgentName,
SQLDMO_LPCSTR SessionID,
long lEstimatedNumRecords,
LPSQLDMOQUERYRESULTS* ppResults);
Returns

The EnumLogReaderAgentSessionDetails2 method differs from the EnumLogReaderAgentSessionDetails 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.
