EnumGeneratedSubsetFilters Method
Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement et prévoyez de modifier les applications qui utilisent actuellement cette fonctionnalité.
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.
Syntaxe
object.EnumGeneratedSubsetFilters(Article,SubsetFilterClause)as QueryResults
Parts
object
Expression that evaluates to an object in the Applies To list.Article
String that identifies an article in the publication by name.SubsetFilterClause
String of 1,002 characters or less that specifies a filter clause to apply to the article. Use an empty string to enable test generation of default filter clauses.
Prototype (C/C++)
HRESULT EnumGeneratedSubsetFilters(
LPSQLDMOQUERYRESULTS* ppResults,
SQLDMO_LPCSTR szArticle,
SQLDMO_LPCSTR szSubsetFilterClause);
Returns
A QueryResults object that contains one result set defined by these columns.
Column |
Data type |
Description |
|---|---|---|
article name |
nvarchar(129) |
Name of the article that contains the joined from table. |
base table name |
nvarchar(129) |
Name of the table joined to in the filter clause. |
base table owner |
nvarchar(129) |
Name of the owner of the table joined to in the filter clause. |
filtername |
nvarchar(129) |
Name of the filter. |
join article name |
nvarchar(129) |
Name of the article on which the filter is defined. |
join_filterclause |
nvarchar(1001) |
Transact-SQL WHERE clause defining the filter. |
join_filterid |
integer |
System-generated identifier. |
join table name |
nvarchar(129) |
Name of the table joined from in the filter clause. |
join table owner |
nvarchar(129) |
Name of the owner of the table joined from in the filter clause. |
join_unique_key |

When 1, the filter depends on a unique or key value. When 0, the filter does not depend on a unique value. |
Notes
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.
