LastOccurrenceDate Property
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The LastOccurrenceDate property identifies the most recent date on which a SQL Server Agent alert was raised.

For C/C++, two SQL Distributed Management Objects (SQL-DMO) functions implement the LastOccurrenceDate property. The GetLastOccurrenceDate and SetLastOccurrenceDate functions represent only the date portion of the SQL Server Agent alert occurrence date. The time portion is represented by the LastOccurrenceTime property. |
Замечания
If SQL-DMO uses a scaled long integer to represent a date, 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.
SQL Server Agent maintains historical data for alerts raised and handled by the agent. The date of last occurrence is one piece of historical information maintained.
