EnumJobHistory Method
后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
The EnumHistory method returns a QueryResults object that enumerates the execution history of all Microsoft SQL Server Agent jobs.
语法
object
.EnumJobHistory( [ JobHistoryFilter ] )as QueryResults
Parts
- object
Expression that evaluates to an object in the Applies To list.
- JobHistoryFilter
Optional. A JobHistoryFilter object that restricts result set membership.
Prototype (C/C++)
HRESULT EnumJobHistory(
LPSQLDMOQUERYRESULTS* ppResults,
LPSQLDMOJOBHISTORYFILTER pJobHistoryFilter = NULL);
Returns
A QueryResults object that contains one result set defined by these columns.

备注
The result set column run_date represents the execution date as a scaled long integer. The integer is built as a sum of the year scaled by 10000, the month scaled by 100, and the day. For example, the date April 19, 1997 is represented by the long integer value 19970419.
The result set column run_time represents execution time as a scaled long integer. The integer is built as a sum of the hour scaled by 10000, the minute scaled by 100, and the seconds. The value uses a 24-hour clock. For example, the time 1:03:09 P.M. is represented by the long integer value 130309.
Membership in the result set is restricted using the optionally specified JobHistoryFilter object. For more information, see JobHistoryFilter Object.
