  • Artikkeli

Applies to: SQL Server

Marks the current open transaction to be a subscription-level validation transaction for the specified subscriber. This stored procedure is executed at the Publisher on the publication database.

Transact-SQL syntax conventions

Syntax

sp_marksubscriptionvalidation
    [ @publication = ] N'publication'
    , [ @subscriber = ] N'subscriber'
    , [ @destination_db = ] N'destination_db'
    [ , [ @publisher = ] N'publisher' ]
[ ; ]

Arguments

[ @publication = ] N'publication'

The name of the publication. @publication is sysname, with no default.

[ @subscriber = ] N'subscriber'

The name of the Subscriber. @subscriber is sysname, with no default.

[ @destination_db = ] N'destination_db'

The name of the destination database. @destination_db is sysname, with no default.

[ @publisher = ] N'publisher'

Specifies a non-SQL Server Publisher. @publisher is sysname, with a default of NULL.

@publisher shouldn't be used for a publication that belongs to a SQL Server Publisher.

Return code values

0 (success) or 1 (failure).

Remarks

sp_marksubscriptionvalidation is used in transactional replication.

sp_marksubscriptionvalidation doesn't support non-SQL Server Subscribers.

For non-SQL Server Publishers, you can't execute sp_marksubscriptionvalidation from within an explicit transaction. This is because explicit transactions aren't supported over the linked server connection used to access the Publisher.

sp_marksubscriptionvalidation must be used together with sp_article_validation, specifying a value of 1 for @subscription_level, and can be used with other calls to sp_marksubscriptionvalidation to mark the current open transaction for other subscribers.

Permissions

Only members of the sysadmin fixed server role or db_owner fixed database role can execute sp_marksubscriptionvalidation.

Examples

The following query can be applied to the publishing database to post subscription-level validation commands. These commands are picked up by the Distribution Agents of specified Subscribers. The first transaction validates article art1, while the second transaction validates art2. The calls to sp_marksubscriptionvalidation and sp_article_validation are encapsulated in a transaction. We recommend only one call to sp_article_validation per transaction. This is because sp_article_validation holds a shared table lock on the source table during the transaction. You should keep the transaction short to maximize concurrency.
