Parametri

columnName
A String value that specifies the name of the column to be added.

typeText
A String value that contains the syntax that follows the column_name parameter in the ALTER TABLE statement in Transact-SQL.

addType
An AddColumnOption object value that specifies whether to include the column in some, all, or no publications. If Some is specified, the publicationNames parameter cannot be empty.

publicationNames
A String array that contains the names of publications to which the column is to be included. This parameter is used only when addType is Some.

schemaChangeScript
An optional String value that specifies a schema change script to propagate to the Subscriber. This is only valid for transactional and snapshot publications. Use null or empty string if you do not want to specify this parameter.

Osservazioni

This method is supported for backward compatibility. Use schema change replication when adding columns to or removing columns from a published table. For more information, see Modifiche allo schema nei database di pubblicazione.

The ReplicationAddColumn method can only be called by members of the sysadmin fixed server role at the Publisher of by members of the db_owner fixed database role on the publication database.

Calling ReplicationAddColumn is equivalent to executing sp_repladdcolumn (Transact-SQL).

This method is available on instances of SQL Server 2000 and SQL Server 2005.

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

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
