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 where foo.foo_id = foo_old.foo_id;
ERRR: missing FRM-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,

Does

update foo
set foo.foo_name2 = foo_old.foo_name2
from foo_old
where foo.foo_id = foo_old.foo_id;

work for you?

Thanks to all for pointing out the FRM clause.!

"UPDATE foo set foo_name2 = foo_old.foo_name2 FRM foo_old WHERE foo.foo_id = foo_old.foo_id;" did the trick.

For some reason I keep forgetting that bit. Especially when under stress in the wee hours of the morn. Back to sleep ZZZzzzzZZZZ

And thanks again !
