Transact-SQL syntax conventions

Syntax

sp_adjustpublisheridentityrange
    [ [ @publication = ] N'publication' ]
    [ , [ @table_name = ] N'table_name' ]
    [ , [ @table_owner = ] N'table_owner' ]
[ ; ]

Arguments

[ @publication = ] N'publication'

The name of the publication in which new identity ranges are reallocated. @publication is sysname, with a default of NULL.

[ @table_name = ] N'table_name'

The name of the table in which new identity ranges are reallocated. @table_name is sysname, with a default of NULL.

[ @table_owner = ] N'table_owner'

The owner of the table at the Publisher. @table_owner is sysname, with a default of NULL.

Return code values

0 (success) or 1 (failure).

Remarks

sp_adjustpublisheridentityrange is used in all types of replication.

For a publication that has the auto identity range enabled, the Distribution Agent or Merge Agent is responsible for automatically adjusting the identity range in a publication based on its threshold value. However, if for some reason the Distribution Agent or Merge Agent wasn't run for some time, and identity range resources are consumed heavily to the point of threshold, you can call sp_adjustpublisheridentityrange to allocate a new range of values for a Publisher.

When you execute sp_adjustpublisheridentityrange, either @publication or @table_name must be specified. If both or neither are specified, an error is returned.

Permissions

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