Transact-SQL syntax conventions

Syntax

sp_get_redirected_publisher
    [ @original_publisher = ] N'original_publisher'
    , [ @publisher_db = ] N'publisher_db'
    [ , [ @bypass_publisher_validation = ] bypass_publisher_validation ]
    [ , [ @multi_subnet_failover = ] multi_subnet_failover ]
[ ; ]

Arguments

[ @original_publisher = ] N'original_publisher'

The name of the instance of SQL Server that originally published the database. @original_publisher is sysname, with no default.

[ @publisher_db = ] N'publisher_db'

The name of the database being published. @publisher_db is sysname, with no default.

[ @bypass_publisher_validation = ] bypass_publisher_validation

Used to bypass validation of the redirected publisher. If 0, validation is performed. If 1, validation isn't performed. @bypass_publisher_validation is bit, with a default of 0.

[ @multi_subnet_failover = ] multi_subnet_failover

Applies to: SQL Server 2022 (16.x) CU 10 and later versions

Used to pass information for the creation of the dynamic linked server. If 0, the dynamic linked server isn't created with the MultiSubnetFailover parameter. If 1, the dynamic linked server is created with the MultiSubnetFailover parameter as 1. @multi_subnet_failover is bit, with a default of 0.

Return code values

0 (success) or 1 (failure).

Result set

Column name Data type Description
redirected_publisher sysname The name of the publisher after redirection.
error_number int The error number of the validation error.
error_severity int The severity of the validation error.
error_message nvarchar(4000) The text of the validation error message.

Remarks

redirected_publisher returns the current publisher name. Returns NULL if the publisher and publishing databases aren't redirected using sp_redirect_publisher.

If validation isn't requested or if no entry exists for the publisher and the publishing database, error_number and error_severity return 0 and error_message returns NULL.

If validation is requested, the validation stored procedure sp_validate_redirected_publisher is called to verify that the target of the redirection is a suitable host for the publishing database. If the validation succeeds, sp_get_redirected_publisher returns the redirected publisher name, 0 for the error_number and error_severity columns, and NULL in the error_message column.

If validation is requested and fails, the redirected publisher name is returned along with error information.

Permissions

Caller must either be a member of the sysadmin fixed server role, the db_owner fixed database role for the distribution database, or a member of a publication access list for a defined publication associated with the publisher database.
