srv_rpcnumber (Extended Stored Procedure API)
This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Use CLR integration instead.
Returns the number component for the current remote stored procedure call.
This function returns only the number component of the remote stored procedure. It does not include the optional specifiers for owner, remote stored procedure name, and database name.
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
