创建只能在当前连接中访问的（temp？）表

I want to enforce row-level security for any client connecting to a particular SQL Server database (just one database). I don't want to impose any particular set up required to happen on the client side (because this would mean that a client can set up itself so that it would have access to anything - which of course would be bad; BTW, the client is a WinApp that connects using either Windows Auth or SQL Auth). I basically want this to be transparent to any client. The client should not even know this is happening. cl
