    [ @proxy_id = ] proxy_id,
    [ @proxy_name = ] 'proxy_name',
    [ @subsystem_id = ] subsystem_id,
    [ @subsystem_name = ] 'subsystem_name'

Arguments

[ @proxy_id = ] proxy_id
The identification number of the proxy to list information for. The proxy_id is int, with a default of NULL. Either the id or the proxy_name may be specified.
[ @proxy_name = ] 'proxy_name'
The name of the proxy to list information for. The proxy_name is sysname, with a default of NULL. Either the id or the proxy_name may be specified.
[ @subsystem_id = ] subsystem_id
The identification number of the subsystem to list information for. The subsystem_id is int, with a default of NULL. Either the subsystem_id or the subsystem_name may be specified.
[ @subsystem_name = ] 'subsystem_name'
The name of the subsystem to list information for. The subsystem_name is sysname, with a default of NULL. Either the subsystem_id or the subsystem_name may be specified.

Return Code Values

0 (success) or 1 (failure)

Result Sets

Column name	Data type	Description
subsystem_id	int	Subsystem identification number.
subsystem_name	sysname	The name of the subsystem.
proxy_id	int	Proxy identification number.
proxy_name	sysname	The name of the proxy.

Remarks

When no parameters are provided, sp_enum_proxy_for_subsystem lists information about all proxies in the instance for every subsystem.

When a proxy id or proxy name is provided, sp_enum_proxy_for_subsystem lists subsystems that the proxy has access to. When a subsystem id or subsystem name is provided, sp_enum_proxy_for_subsystem lists proxies that have access to that subsystem.

When both proxy information and subsystem information is provided, the result set returns a row if the proxy specified has access to the subsystem specified.

This stored procedure is located in msdb.

Permissions

Execution permissions for this procedure default to members of the sysadmin fixed server role.

Examples

A. Listing all associations

The following example lists all permissions established between proxies and subsystems for the current instance.

USE msdb ;
GO

EXEC dbo.sp_enum_proxy_for_subsystem ;
GO

B. Determining if a proxy has access to a specific subsystem

The following example returns a row if the proxy Catalog application proxy has access to the ActiveScripting subsystem. Otherwise, the example returns an empty result set.

USE msdb ;
GO

EXEC dbo.sp_enum_proxy_for_subsystem
    @subsystem_name = 'ActiveScripting',
    @proxy_name = 'Catalog application proxy' ;
GO
