project_num=15Hi 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;
