EnumMergeAgentSessions2 Method

The EnumMergeAgentSessions2 method returns a QueryResults object that enumerates execution status data for the merge replication agent specified.

Applies To
DistributionPublisher2 Object
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.

Constant Value Description
SQLDMOSession_All 1 Output contains log information for all sessions for agent
SQLDMOSession_Errors 2 Output contains log information only for those execution attempts ending in error

Returns

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

Column Data type Description
average_rows integer Average number of rows per second.
action_count integer Number of session history records.
comments nvarchar(256) Descriptive text.
duration integer Elapsed time of the session.
error_id integer When nonzero, Microsoft® SQL Server™ 2000 error message number.
publisher_conflicts integer Number of conflicts at the Publisher.
publisher_deletecount integer Number of deletes at the Publisher.
publisher_insertcount integer Number of inserts at the Publisher.
publisher_updatecount integer Number of updates at the Publisher.
runstatus integer Executing state. Interpret using SQLDMO_TASKSTATUS_TYPE.
start_time nvarchar(26) Date and time of last scheduled execution.
subscriber_conflicts integer Number of conflicts at the Subscriber.
subscriber_deletecount integer Number of deletes at the Subscriber.
subscriber_insertcount integer Number of inserts at the Subscriber.
subscriber_updatecount integer Number of updates at the Subscriber.
time nvarchar(26) Date and time of message logging.

Remarks

In the result set, date, and time data returned in start_time and 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).

For example, the value 19990911 18:12:00.000 is interpreted as 6:12 P.M., September 11, 1999.

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.
