sp_article_validation
Initiates a data validation request for the specified article. This stored procedure is executed at the Publisher on the publication database.
Syntax
sp_article_validation [ @publication = ] 'publication'
[ , [ @article = ] 'article' ]
[ , [ @rowcount_only = ] type_of_check_requested ]
[ , [ @full_or_fast = ] full_or_fast ]
[ , [ @shutdown_agent = ] shutdown_agent ]
[ , [ @subscription_level = ] subscription_level ]
[ , [ @reserved = ] reserved ]
Arguments
[@publication =] 'publication'
Is the name of the publication in which the article exists. publication is sysname, with no default.
[@article =]'article'
Is the name of the article to change. article is sysname, with no default.
[@rowcount_only =] type_of_check_requested
Specifies if only the rowcount for the table is returned. . type_of_check_requested is smallint, with a default of 1. If 0, perform a SQL Server 7.0 compatible checksum. If 1, perform a rowcount check only. If 2, perform a rowcount and checksum.
[@full_or_fast =] full_or_fast
Is the method used to calculate the rowcount. full_or_fast is tinyint, and can be one of these values.
| Value | Description |
|---|---|
| 0 | Performs full count using COUNT(*). |
| 1 | Performs fast count from sysindexes.rows. Counting rows in sysindexes is faster than counting rows in the actual table. However, sysindexes is updated lazily, and the rowcount may not be accurate. |
| 2 (default) | Performs conditional fast counting by first trying the fast method. If fast method shows differences, reverts to full method. If expected_rowcount is NULL and the stored procedure is being used to get the value, a full COUNT(*) is always used. |
[@shutdown_agent =] shutdown_agent
Specifies if the Distribution agent should shut down immediately upon completion of the validation. shutdown_agent is bit, with a default of 0. If 0, the Distribution Agent does not shut down. If 1, the Distribution Agent shuts down after the article is validated.
[@subscription_level =] subscription_level
Specifies whether or not the validation is picked up by a set of subscribers. subscription_level is bit, with a default of 0. If 0, validation will be applied to all Subscribers. If 1, validation will only be applied to a subset of the Subscribers specified by calls to sp_marksubscriptionvalidation in the current open transaction.
[@reserved =] reserved
For internal use only.
Return Code Values
0 (success) or 1 (failure)
Remarks
sp_article_validation is used in snapshot replication and transactional replication.
sp_article_validation causes validation information to be gathered on the specified article and posts a validation request to the transaction log. When the Distribution Agent receives this request, the Distribution Agent compares the validation information in the request to the Subscriber table. The results of the validation are displayed in the Replication Monitor and in SQL Server Agent alerts.
Permissions
Only members of the sysadmin fixed server role or db_owner fixed database role can execute sp_article_validation.
