Hello
you have to parse a sqlerrm variable
CREATE OR REPLACE FUNCTION public.test(a integer, b integer)
RETURNS void
LANGUAGE plpgsql
AS $function$
begin
insert into foo values(a,b);
exception when unique_violation then
raise notice '% %', sqlerrm, sqlstate;
end;
$function$
postgres=# select test(4,2);
NOTICE: duplicate key value violates unique constraint "foo_b_key" 23505
test
──────
(1 row)
Time: 9.801 ms
postgres=# select test(3,2);
NOTICE: duplicate key value violates unique constraint "foo_a_key" 23505
test
──────
(1 row)
Time: 17.167 ms
