Исключения

Исключение Условие
ApplicationException

When you attempt to set the DatabaseName property for an existing article.
ArgumentException

Замечания

The DatabaseName property is a read/write property.

The DatabaseName property must be set before the Create method is called to create the article on the server. Attempting to set this property for an existing article generates an exception.

The DatabaseName property must be set to the name of the distribution database for non-SQL Server publications.

The DatabaseName property can be retrieved by members of the sysadmin fixed server role at the Publisher and at the Subscriber (for republishing Subscribers). It can also be retrieved by members of the db_owner fixed database role on the publication database and by users who are members of the PAL. For a MergeArticle object, this property can also be retrieved by members of the replmonitor fixed database role on the Distributor.

The DatabaseName property can be set by members of the sysadmin fixed server role at the Publisher. It can also be set by members of the db_owner fixed database role on the publication database.

Retrieving DatabaseName is equivalent to executing sp_helparticle (Transact-SQL) for transactional or snapshot replication or executing sp_helpmergearticle (Transact-SQL) for merge replication.

Setting DatabaseName is equivalent to executing sp_addarticle (Transact-SQL) for transactional or snapshot replication, or executing sp_addmergearticle (Transact-SQL) for merge replication.

The DatabaseName property is available with SQL Server 2005, SQL Server 2000, and SQL Server 7.0..

This namespace, class, or member is supported only in the .NET Framework 2.0.
