Question

我是否可以在SQL Server 2008 R2中仅启用特定用户的TCP连接，或者在另一方面，是否可以阻止某些用户使用TCP远程连接到SQL Server？

Answer 1

我会使用Logon Triggers功能来完成此任务。

Answer 2

CREATE TRIGGER remote_connection_limit_trigger
ON ALL SERVER WITH EXECUTE AS 'sa'
FOR LOGON
AS
BEGIN
DECLARE @result XML
SET @result = EVENTDATA()
DECLARE @spid NVARCHAR(MAX)

SET @spid = @result.value('(/EVENT_INSTANCE/SPID)[1]', 'nvarchar(MAX)')

DECLARE @connectionType NVARCHAR(MAX)
SELECT @connectionType = net_transport FROM sys.dm_exec_connections WHERE  session_id = @spid


IF @connectionType = 'TCP' AND ORIGINAL_LOGIN() <> 'temp_remote_user'
    ROLLBACK;
END;

仅为特定用户启用SQL Server的TCP连接
