sys.tcp_endpoints (Transact-SQL)
Contains one row for each TCP endpoint that is in the system. The endpoints that are described by sys.tcp_endpoints provide an object to grant and revoke the connection privilege. The information that is displayed regarding ports and IP addresses is not used to configure the protocols and may not match the actual protocol configuration. To view and configure protocols, use SQL Server Configuration Manager.
Column name |
Data type |
Description |
|---|---|---|
<inherited columns> |
Inherits columns from sys.endpoints. |
|
port |
int |
The port number that the endpoint is listening on. Is not nullable. For dynamic ports, returns 0. |
is_dynamic_port |
bit |
1 = Port number was dynamically assigned. Is not nullable. |
ip_address |
nvarchar(45) |
Listener IP address as specified by the LISTENER_IP clause. Is nullable. |
Remarks
Execute the following query to gather information about the endpoints and connections. Endpoints without current connections or without TCP connections will appear with NULL values. Add the WHERE clause WHERE des.session_id = @@SPID to return information about the current connection.
SELECT des.login_name, des.host_name, program_name, dec.net_transport, des.login_time,
e.name AS endpoint_name, e.protocol_desc, e.state_desc, e.is_admin_endpoint,
t.port, t.is_dynamic_port, dec.local_net_address, dec.local_tcp_port
FROM sys.endpoints AS e
LEFT JOIN sys.tcp_endpoints AS t
ON e.endpoint_id = t.endpoint_id
LEFT JOIN sys.dm_exec_sessions AS des
ON e.endpoint_id = des.endpoint_id
LEFT JOIN sys.dm_exec_connections AS dec
ON des.session_id = dec.session_id;
Permissions
In SQL Server 2005 and later versions, the visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
