Обсуждение: ERROR: column "id" does not exist

Hy

i have a  problem with the following statement:

SELECT MAX(id) FROM apconfig;

if i send this statement i got the following error:

ERROR: column "id" does not exist

Can anyone explain me this error? There is the column id, and there are
also entries in it.

thx

The column might have a different case or possibly leading or
trailing spaces, in which case you'll have to quote it verbatim.
What does \d apconfig show?  If that doesn't show the problem
then try this:

SELECT quote_ident(attname) FROM pg_attribute
WHERE attrelid = 'apconfig'::regclass;
