Syntax
sp_publication_validation
[ @publication = ] N'publication'
[ , [ @rowcount_only = ] rowcount_only ]
[ , [ @full_or_fast = ] full_or_fast ]
[ , [ @shutdown_agent = ] shutdown_agent ]
[ , [ @publisher = ] N'publisher' ]
[ ; ]
Arguments
[ @publication = ] N'publication'
The name of the publication. @publication is sysname, with no default.
[ @rowcount_only = ] rowcount_only
Specifies whether to return only the rowcount for the table. @rowcount_only is smallint, and can be one of the following values.
| Value | Description |
|---|---|
0 |
Perform a SQL Server 7.0 compatible checksum. Note: When an article is horizontally filtered, a rowcount operation is performed instead of a checksum operation. |
1 (default) |
Perform a rowcount check only. |
2 |
Perform a rowcount and binary checksum. |
[ @full_or_fast = ] full_or_fast
The method used to calculate the rowcount. @full_or_fast is tinyint, and can be one of the following values.
| Value | Description |
|---|---|
0 |
Does full count using COUNT(*). |
1 |
Does fast count from sysindexes.rows. Counting rows in sys.sysindexes is faster than counting rows in the actual table. However, because sys.sysindexes is lazily updated, the rowcount might not be accurate. |
2 (default) |
Does 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 whether the Distribution Agent should shut down immediately upon completion of the validation. @shutdown_agent is bit, with a default of 0.
- If
0, the replication agent doesn't shut down. - If
1, the replication agent shuts down after the last article is validated.
[ @publisher = ] N'publisher'
Specifies a non-SQL Server Publisher. @publisher is sysname, with a default of NULL.
@publisher shouldn't be used when requesting validation on a SQL Server Publisher.
Return code values
0 (success) or 1 (failure).
Remarks
sp_publication_validation is used in transactional replication.
sp_publication_validation can be called at any time after the articles associated with the publication are activated. The procedure can be run manually (one time) or as part of a regularly scheduled job that validates the data.
If your application has immediate-updating Subscribers, sp_publication_validation might detect spurious errors. sp_publication_validation first calculates the rowcount or checksum at the Publisher and then at the Subscriber. Because the immediate-updating trigger could propagate an update from the Subscriber to the Publisher after the rowcount or checksum is completed at the Publisher, but before the rowcount or checksum is completed at the Subscriber, the values could change. To ensure that the values at the Subscriber and Publisher don't change while validating a publication, stop the Microsoft Distributed Transaction Coordinator (MS DTC) service at the Publisher during validation.
Permissions
Only members of the sysadmin fixed server role or the db_owner fixed database role can execute sp_publication_validation.
