Good evening, I am trying to take a JSONB object (comes from an HTTP cookie set by my app) and add a property "uid" to it, which should hold an integer:
CREATE OR REPLACE FUNCTION words_get_user( in_users jsonb, OUT out_user jsonb ) RETURNS jsonb AS $func$ DECLARE _user jsonb; _uid integer; _banned boolean; _removed boolean; BEGIN -- in_users must be a JSON array with at least 1 element IF in_users IS NULL OR JSONB_ARRAY_LENGTH(in_users) = 0 THEN RAISE EXCEPTION 'Invalid users = %', in_users; END IF; -- ensure that every record has a valid auth FOR _user IN SELECT * FROM JSONB_ARRAY_ELEMENTS(in_users) LOOP IF NOT words_valid_user((_user->>'social')::int, _user->>'sid', _user->>'auth') THEN RAISE EXCEPTION 'Invalid user = %', _user; END IF; IF out_user IS NULL THEN SELECT uid, u.banned_until > CURRENT_TIMESTAMP, u.removed INTO STRICT _uid, _banned, _removed FROM words_social s LEFT JOIN words_users u USING(uid) WHERE s.social = (_user->>'social')::int AND s.sid = _user->>'sid'; IF _banned THEN RAISE EXCEPTION 'Banned user = %', _user; END IF; IF _removed THEN RAISE EXCEPTION 'Removed user = %', _user; END IF; out_user := JSONB_INSERT(_user, '{uid}', _uid); END IF; END LOOP; END $func$ LANGUAGE plpgsql; Unfortunately, when I run my stored function it fails: words_en=> select out_user from words_get_user('[{"given":"Abcde1","social":1,"auth":"xxx","stamp":1480237061,"sid":"aaaaa","photo":" https://vk.com/images/camera_200.png "},{"given":"Abcde2","social":2,"auth":"xxx","stamp":1477053188,"sid":"aaaaa"},{"given":"Abcde3","social":3,"auth":"xxx","stamp":1477053330,"sid":"aaaaa"}]'::jsonb); ERROR: function jsonb_insert(jsonb, unknown, integer) does not exist LINE 1: SELECT JSONB_INSERT(_user, '{uid}', _uid) ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. QUERY: SELECT JSONB_INSERT(_user, '{uid}', _uid) CONTEXT: PL/pgSQL function words_get_user(jsonb) line 44 at assignment What is missing here please?
