EnumGeneratedSubsetFilters Method

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 EnumGeneratedSubsetFiltersmethod applies the filter clause specified to the article indicated, performs temporary filter generation, and then returns a QueryResults object that enumerates default filters generated by the test case specified.

Синтаксис

Prototype (C/C++)

LPSQLDMOQUERYRESULTS* ppResults,

Column

Data type

Замечания

The EnumGeneratedSubsetFiltersmethod explicitly begins a transaction prior to generating any filters, and then explicitly rolls back the transaction when the result set is generated. No permanent change is made to publication or article definition by the method.
