EnumLogReaderAgentSessionDetails2 Method

Esta característica se quitará en una versión futura de Microsoft SQL Server. Evite utilizar esta característica en nuevos trabajos de desarrollo y tenga previsto modificar las aplicaciones que actualmente la utilizan.

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

Sintaxis

object.EnumLogReaderAgentSessionDetails2(AgentName,SessionID,lEstimatedNumRecords)as QueryResults

Parts

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

• AgentName
  String that identifies a Log Reader Agent session 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 EnumLogReaderAgentSessions2 method.

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

Prototype (C/C++)

HRESULT EnumLogReaderAgentSessionDetails2(
SQLDMO_LPCSTR AgentName,
SQLDMO_LPCSTR SessionID,
long lEstimatedNumRecords,
LPSQLDMOQUERYRESULTS* ppResults);

Returns

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

Column	Data type	Description
runstatus	integer	Executing state. Interpret using SQLDMO_TASKSTATUS_TYPE.

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.
