Hi!
You're missing a table declaration for the table foo_old. You might try this:
update foo set foo.foo_name2= (SELECT foo_old.foo_name2 FROM foo_old where
foo.foo_id = foo_old.foo_id);
Kind regards
Markus

Betreff: [GENERAL] Need to update all entries of one table based on an
earlier backup
For reasons best left unmentioned, I need to update entries in a table
from a backup; I need to do all entries.
For reasons eluding my sleep deprived eyes this fails in every
variation I can think of:
update foo set foo.foo_name2=foo_old.foo_name2 where foo.foo_id =
foo_old.foo_id;
ERROR: missing FROM-clause entry for table "foo_old"
Could someone please hit me with a clue-stick ? This is crucial and yet
I am stumbling over something. Since I am not updating foo_old I am baffled as
to what this messsage really means. I've tried "where foo_old.foo_id =
foo.foo_id ... same message.
TIA,
