[SQL] Simultaneous Connection Problem

[Webb Sprague]

I have a table that is sequence_number (my PK), session_start_time, and
session_stop_stime.  I would like to query it to determine the max number
of simultaneous sessions.  Has anyone conquered a problem like this?  It
seems like it should be in a book somewhere, but I haven't found it yet.

Thanks,
