2.2.1.6 Remote Procedure Call

To execute a remote procedure call (RPC) on the server, the client sends an RPC message data stream to the server. This is a binary stream that contains the RPC name or numeric identifier, options, and parameters. RPCs MUST be in a separate TDS message and not intermixed with SQL statements. There can be several RPCs in one message. For more details, see section 2.2.6.6.
