How to get a current session's host(ip and port of the client) and user name in a select

I would like to know how to get the data from a 'select host, user
from INFORMATION_SCHEMA.PROCESSLIST' for only the current session.

Basically I'm trying to make a 'BEFORE INSERT ON' trigger that will
fill in fcUser and fcHost (varchar) fields of a table with the
inserter's username and host. I tried using the select above but it
returns multiple rows for people with the process privilege. I looked
around for a local variable but saw no host or user var. Did i just
miss it?

I'm using the 5.x line.
Thanks,
Tim

select user();

If you must have two fields, split the result at the '@'.

My MySQL doesn't seem to have a PROCESSLIST table. If yours does, you
might find connection_id() useful.

Thanks! That solves it. I was looking for a variable but turns out to
be a built-in function. Searching the mysql manual for connection_id()
netted me '12.10.3. Information Functions'. Everything I needed.
