Subject: [SQL] ERROR: SELECT query has no destination for result data

Hi list,

I have a function like this:

Create OR REPLACE Function base.inserirPontos(char(1), varchar(255), numeric(12,2), int8, int8, int8 ) returns int4 as
$$
declare
Operacao alias for $1;
Numero_nota alias for $2;
Valor_nota alias for $3;
PontoVenda_Emissor alias for $4;
Cardpass alias for $5;
Cx_Id alias for $6;

begin

-- Validando parâmetros passados na função

if Operacao <> 'C' then
return 1;
else
select count(id) as numRegistros from base.emissor_ponto_venda where id = PontoVenda_Emissor;
if numRegistros = 0 then
return 2;
else
insert into base.pontos values (nextval('base.ponto_id'), now(), Operacao, Numero_nota, Valor_nota, PontoVenda_Emissor, CartaoId(Cardpass), Cx_id);
return 0;
end if;
end if;
end

$$
LANGUAGE 'plpgsql'

And I am getting the following result when I try to insert using the function:

select base.inserirPontos('C', '123456789', 12.5, 1, 9877000000944005, 104)

ERROR: SELECT query has no destination for result data
HINT: If you want to discard the results, use PERFORM instead.
CONTEXT: PL/pgSQL function "inserirpontos" line 17 at SQL statement

What I did wrong ? Any suggestion is quite good please.

ps:
