EnumSnapshotAgentSessions2 Method

Microsoft SQL Server의 이후 버전에서는 이 기능이 제거됩니다. 새 개발 작업에서는 이 기능을 사용하지 말고, 현재 이 기능을 사용하는 응용 프로그램은 수정하십시오.

The EnumSnapshotAgentSessions2 method returns a QueryResults object that enumerates session information for Snapshot Agents used by a Distributor.

Parts

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

• AgentName
  String that identifies a Snapshot Agent by name.

• SessionType
  Long integer that indicates session type using SQLDMO_ SESSION_TYPE.

• 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 EnumSnapshotAgentSessions2(
SQLDMO_LPCSTR AgentName,
SQLDMO_SESSION_TYPE SessionType,
long SessionDuration,
long lEstimatedNumRecords,
LPSQLDMOQUERYRESULTS* ppResults);

Returns

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

Column	Data type	Description
action_count	integer	Number of session history records.
comments	nvarchar(256)	Descriptive text.
delivered_commands	integer	Cumulative number of commands delivered in the session.
delivery_rate	float	Average number of commands delivered per second.
duration	integer	Elapsed time of the session in seconds.
error_id	integer	When nonzero, Microsoft SQL Server error message number.
runstatus	integer	Executing state. Interpret using SQLDMO_TASKSTATUS_TYPE.
start_time	nvarchar(26)	Date and time of last scheduled execution.
time	nvarchar(26)	Date and time of message logging.

주의

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).
ss	Represents the second in two digits (zero padded).
fff	Represents the fractional part of the second in three digits.

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

The EnumSnapshotAgentSessions2 method differs from the EnumSnapshotAgentSessions 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.
