I allways get the same error :
ERROR: set-valued function called in context that cannot accept a set
It seems to not accept the "(''test'')". Maybe i made a mistake by
adding the plpgsql langage, but i follow the documentation about that.
If i try to change the insert by "INSERT INTO categorie (id_categorie)
VALUES (''test'');" i got an error msg that "test" is not an integer.
(id_categorie is the primary key of the table).
thx in advance,
regards,
