Members
| Member name | Description |
|---|---|
| AggregateSchemaOnly | The source object for the published article is the schema definition of a user-defined aggregate function. |
| FunctionSchemaOnly | The source object for the published article is the schema definition of a user-defined function. |
| IndexedView | The source object for the published article is an indexed view. |
| IndexedViewLogBased | The source object for the published article is an indexed view, and data changes are read from the log. |
| IndexedViewLogBasedManualBoth | The source object for the published article is an indexed view. Data changes are read from the transaction log. The user defines the object that provides the initial snapshot data for the article and the stored procedure that filters the article horizontally. |
| IndexedViewLogBasedManualFilterProc | The source object for the published article is an indexed view. Data changes are read from the transaction log, and the user defines the stored procedure that filters the article horizontally. |
| IndexedViewLogBasedManualSyncView | The source object for the published article is an indexed view. Data changes are read from the transaction log, and the user defines the object that provides the initial snapshot data for the article. |
| IndexedViewSchemaOnly | The source object for the published article is the schema definition of an indexed view. |
| LogBased | The source object for the published article is a table. Data changes are read from the transaction log. |
| LogBasedManualBoth | The source object for the published article is a table. Data changes are read from the transaction log. The user defines the object that provides the initial snapshot data for the article and the stored procedure that filters the article horizontally. |
| LogBasedManualFilterProc | The source object for the published article is a table. Data changes are read from the transaction log, and the user defines the stored procedure that filters the article horizontally. |
| LogBasedManualSyncView | The source object for the published article is a table. Data changes are read from the transaction log, and the user defines the object that provides the initial snapshot data for the article. |
| ManualFilterProc | The user defines the stored procedure that filters the article horizontally. |
| ManualSyncView | The user defines the object that provides the initial snapshot data for the article. |
| ProcExecution | The source for the published article is the execution of a stored procedure. The commands in the stored procedure are replicated to the Subscriber. |
| ProcSchemaOnly | The source object for the published article is the schema definition of a stored procedure. |
| SerializableProcExecution | The source for the published article is the execution of a stored procedure. Only the commands of the stored procedure that are within the context of a transaction that can be serialized are replicated to the Subscriber. |
| TableBased | The source object for the published article is a table. |
| ViewSchemaOnly | The source object for the published article is the schema definition of a view. |
Notas
The field values of ArticleOptions are equivalent to the supported values of the @type parameter in sp_addarticle (Transact-SQL) and sp_addmergearticle (Transact-SQL).
The ArticleOptions enumeration supports the FlagsAttribute option, which allows a bitwise combination of enumeration values. However, each supported article type has a separate value, so bitwise operations are not required.
Not all ArticleOptions are supported for all types of replication.
This namespace, class, or member is supported only in the Microsoft .NET Framework version 2.0.
