This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

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

Syntax

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.
time	nvarchar(26)	Date and time of message logging.
comments	nvarchar(256)	Descriptive text.
duration	integer	Elapsed time of the session.
delivery_rate	float	Average number of commands delivered per second.
delivery_latency	integer	Latency, in milliseconds, between the transaction entering the distribution database and being applied to the Subscriber.
delivery_time	integer	Cumulative time measurement for delivery in seconds.
delivered_/transactions	integer	Cumulative number of transactions delivered in the session.
delivered_commands	integer	Cumulative number of commands delivered in the session.
average_commands	integer	Average number of commands per transaction delivered in the session.
error_id	integer	When nonzero, Microsoft SQL Server error message number.

Remarks

In the result set, date and time data returned in time is formatted as YYYYMMDD hh:mm:ss.fff.

Date part	Description
YYYY	Represents the year in four digits.
MM	Represents the month in two digits (zero padded).
DD	Represents the day of the month in two digits (zero padded).
hh	Represents the hour using two digits, a twenty-four hour clock (zero padded).
mm	Represents the minute in two digits (zero padded).
ss	Represents the second in two digits (zero padded).

For example, the value 20040512 18:12:00.000 is interpreted as 6:12 P.M., May 12, 2004.

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.
