That query will tell you how many sessions by that name exist in the
database -- meaning that many that were created and have not been
garbage collected yet.

It is nearly impossible to know what sessions are still "active" -- in
terms of what the person browsing considers "active".

The best you can do is come up with some time, say 10 minutes, and
find all session last used within that time and consider those
"active".
