After logging in, a client can ask for:
The name of the server’s character set
The name of the server’s sort order
The character-set definition for the client’s character set
The sort order definition for the client’s sort order
Clients make these requests through the sp_serverinfo system registered procedure, using RPC commands.
In response, Open Server automatically returns the requested information by means of the sp_serverinfo system registered procedure. The Open Server application does not need to take any action at this point, and, in fact, is not aware that the request ever occurred.
