sp_deletetracertokenhistory (Transact-SQL)
Removes tracer token records from the MStracer_tokens (Transact-SQL) and MStracer_history (Transact-SQL) system tables. This stored procedure is executed at the Publisher on the publication database or at the Distributor on the distribution database.
Transact-SQL Syntax Conventions
- [ @publication = ] 'publication'
-
Is the name of the publication in which the tracer token was inserted. publication is sysname, with no default.
- [ @tracer_id = ] tracer_id
-
Is the ID of the tracer token to delete. tracer_id is int, with a default value of NULL. If null, then all tracer tokens belonging to the publication are deleted.
- [ @cutoff_date = ] cutoff_date
-
Specifies a cutoff date such that all tracer tokens inserted into the publication before that date are removed. cutoff_date is datetime, with a default value of NULL.
- [ @publisher = ] 'publisher'
-
The name of the Publisher. publisher is sysname, with a default of NULL.
Note: This parameter should only be specified for non-Microsoft SQL Server Publishers.
- [ @publisher_db = ] 'publisher_db'
-
The name of the publication database. publisher_db is sysname, with a default value of NULL. This parameter is ignored if the stored procedure is executed at the Publisher.
sp_deletetracertokenhistory is used in transactional replication.
When executing sp_deletetracertokenhistory, you can only specify one of tracer_id or cutoff_date. An error occurs when you specify both parameters.
If you do not execute sp_deletetracertokenhistory to remove tracer token metadata, the information will be removed when the regularly scheduled history cleanup occurs.
Tracer token IDs can be determined by executing sp_helptracertokens (Transact-SQL) or by querying the MStracer_tokens (Transact-SQL) system table.
