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 ReadReplicationFailOverMode method retrieves the failover mode for a subscription that uses immediate updating with queued updating as the failover option.

Синтаксис

object
.ReadReplicationFailOverMode(
szPublisher, 
szPublicationDB, 
szPublication )asSQLDMO_REPLFAILOVER_TYPE

Parts

object
Expression that evaluates to an object in the Applies To list.

szPublisher
String that specifies the name of the Publisher.

szPublicationDB

Settings

ReadReplicationFailOverMode returns these values.

Constant	Value	Description
SQLDMOReplFailOver_/Immediate	0	Use the immediate updating option to propagate changes made at Subscribers to the Publisher.
SQLDMOReplFailOver_Queued	1	Use the queued updating option to propagate changes made at Subscribers to the Publisher.

Prototype (C/C++)

HRESULT ReadReplicationFailOverMode(
SQLDMO_LPCSTR pszPublisher, 
SQLDMO_LPCSTR pszPublicationDB, 
SQLDMO_LPCSTR pszPublication, 
SQLDMO_REPLFAILOVER_TYPE *pFailOverMode);

Замечания

The ReadReplicationFailOverMode method should be called on a ReplicationDatabase2 object that represents a subscription database. The szPublisher, szPublicationDB, and szPublication parameters identify a subscription in the subscription database.

An application must use the WriteReplicationFailOverMode method to set the failover mode for a subscription that uses immediate updating with queued updating as the failover option.

Примечание.
If an application calls ReadReplicationFailOverMode on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
