SELECT MAX(sequence) FROM project_log_table WHERE person_num=427 AND

Hi Francisco,
My apologies, I was not completely clear. I will not know any of the
columns in advance. The most recent insert is the result of user input
from a web form, so I won't know what project or what user generated
the last insert. That was why I wandered if that information was
stored anywhere in the system.
wait, so you just want the latest record inserted with -any-
project/person ? add a timestamptz field to your table with default
current_timestamp;
