Re: RETURNS TABLE function returns nothingness - Mailing list pgsql-general

 why doesn't this simple test function return a row with 42, NULL values:

CREATE OR REPLACE FUNCTION words_merge_users_2(

                IN in_users jsonb,

                IN in_ip inet

        ) RETURNS TABLE (

                out_uid integer,

                out_banned varchar

        ) AS

$func$

DECLARE

        _user          jsonb;

        _uids          integer[];

        _created       timestamptz;

        _vip           timestamptz;

        _grand         timestamptz;

        _banned_until  timestamptz;

        _banned_reason varchar;

BEGIN

        out_uid := 42;

END

$func$ LANGUAGE plpgsql;

Here I call it at PostgreSQL 9.5.4 prompt in MacOS:

# select * from words_merge_users_2('[{"given":"Abcde","social":1,"auth":"07f0254f5e55413dec7f32c8ef4ee5d3","stamp":1470237061,"female":0,"sid":"11111"}]                   '::jsonb, '1.1.1.1'::inet);

 out_uid | out_banned 

---------+------------

(0 rows)

Thank you (I am probably missing something very obvious)

There is not RETURN NEXT statement - so output is zero rows.
