Hi,
Hi,
I just cannot see what is wrong with my query:
create table files (id int, name text, prev_name text, ....);
create table fnchanged (id int, name text);
update files f set prev_name = f.name, name = c.name from fnchanges c where f.id = c.id and c.name != f.name
your update statement works for me after changing
from fnchanges
to
from fnchanged
(as written in your create statement) but I've got ERROR: relation "fnchanges" does not exist
instead of a syntax error
--- gets syntax error at "from"
(Using PostgreSQL 10.4 on a NAS box)
Best regards
Wolfgang
kind regards
