sp_add_proxy (Transact-SQL)

Applies to: SQL Server

Adds the specified SQL Server Agent proxy.

Transact-SQL syntax conventions

Syntax

sp_add_proxy
    [ @proxy_name = ] 'proxy_name'
    , [ @enabled = ] is_enabled
    , [ @description = ] 'description'
    , [ @credential_name = ] 'credential_name'
    , [ @credential_id = ] credential_id
    , [ @proxy_id = ] id OUTPUT
[ ; ]

Arguments

[ @proxy_name = ] 'proxy_name'

The name of the proxy to create. The @proxy_name is sysname, with a default of NULL. When the @proxy_name is NULL or an empty string, the name of the proxy defaults to the @credential_name or @credential_id supplied.

[ @enabled = ] is_enabled

Specifies whether the proxy is enabled. The @enabled flag is tinyint, with a default of 1. When @enabled is 0, the proxy isn't enabled, and can't be used by a job step.

[ @description = ] 'description'

A description of the proxy. The description is nvarchar(512), with a default of NULL. The description allows you to document the proxy, but isn't otherwise used by SQL Server Agent. Therefore, this argument is optional.

[ @credential_name = ] 'credential_name'

The name of the credential for the proxy. The @credential_name is sysname, with a default of NULL. Either @credential_name or @credential_id must be specified.

[ @credential_id = ] credential_id

The identification number of the credential for the proxy. The @credential_id is int, with a default of NULL. Either @credential_name or @credential_id must be specified.

[ @proxy_id = ] proxy_id OUTPUT

The proxy identification number assigned to the proxy if created successfully.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

This stored procedure must be run in the msdb database.

A SQL Server Agent proxy manages security for job steps that involve subsystems other than the Transact-SQL subsystem. Each proxy corresponds to a security credential. A proxy might have access to any number of subsystems.

Permissions

This stored procedure is owned by the db_owner role. You can grant EXECUTE permissions for any user, but these permissions may be overridden during a SQL Server upgrade.

Members of the sysadmin fixed security role can create job steps that use any proxy. Use the stored procedure sp_grant_login_to_proxy to grant other logins access to the proxy.

Examples

This example creates a proxy for the credential CatalogApplicationCredential. The code assumes that the credential already exists. For more information about credentials, see CREATE CREDENTIAL.

USE msdb;
GO

EXEC dbo.sp_add_proxy
    @proxy_name = 'Catalog application proxy',
    @enabled = 1,
    @description = 'Maintenance tasks on catalog application.',
    @credential_name = 'CatalogApplicationCredential';
GO
