How to find out if a user is logged in via SQL schema?

I just installed wildfire with MySQL. I’‘d like to be able to be able to determine if a user is logged in via an SQL query but I can’‘t seem to find a table/column where that information is stored. jiveRoster would be a good guess but it’'s empty.

Hi,

Wildfire does not store this information in the database so there is no way to check this using SQL.
