sp_who displays information about all current Adaptive Server users and processes or about a particular user or process. The results of sp_who include the loginame and origname. If a user is operating under a proxy, origname contains the name of the original login. For example, assume that “ralph” executes the following, then executes some SQL commands:
set proxy susie
sp_who returns “susie” for loginame and “ralph” for origname.
sp_who queries the master..sysprocesses system table, which contains columns for the server user ID (suid) and the original server user ID (origsuid).
For more information, see sp_who in the Reference Manual.
