[SQL] Function .. AS..?

[Ing. Jhon Carrillo]

Those instructions are good but i want  to call this function  only  for  " select  consulta_contacto(1)"  nothing more,  Is really necesary to use  "AS ..."?   this is  the call:     select * from  consulta_contacto(1) as (cont_codigo      integer,                                         cont_idpers      varchar,                                         cont_nombre      varchar,                                         cont_apellido    varchar,                                         cont_titulo      varchar,                                         cont_fecnac      timestamp ,                                         cont_codedociv   integer,                                         cont_sexo        char(1),                                         cont_codpais     integer,                                         cont_pw          varchar,                                         cont_empr        varchar,                                         cont_cargo       varchar,                                         cont_pwempr      varchar,                                         cont_aniv        char(5),                                         cont_prof        varchar,                                         cont_trab        char(1),                                         cont_fecgen      timestamp,                                         cont_fecing      timestamp,                                         cont_fuente      char(1),                                         cont_sinc        char(1),                                         cont_codupload   integer);   this is the function:   CREATE OR REPLACE FUNCTION consulta_contacto(integer) RETURNS SETOF RECORD AS ' DECLARE    rec RECORD;    sup INTEGER; BEGIN    FOR rec IN SELECT cont_codigo,cont_idpers, cont_nombre,cont_apellido,cont_titulo,cont_fecnac,cont_codedociv,cont_sexo,cont_codpais,cont_pw,cont_empr,cont_cargo,cont_pwempr,cont_aniv,cont_prof,cont_trab,cont_fecgen,cont_fecing,cont_fuente,cont_sinc,cont_codupload       FROM tbu_contacto      LOOP        RETURN NEXT rec ;      END LOOP;    RETURN ; END; ' LANGUAGE plpgsql;
