[GENERAL] Problem with function parameters

[Alejandro Michelin Salomon \( Adinet \)]

Hi :
 
I have installed Pg 8.08
 
I create this function :
CREATE OR REPLACE FUNCTION CALCULO_VALOR_LIQUIDO_HELPDESK( nTipoDesconto
SMALLINT,
                                                           nTipoComissao
SMALLINT,
                                                           nDesconto
NUMERIC,
                                                           nComissao
NUMERIC,
                                                           nTotal NUMERIC )
RETURNS NUMERIC AS $$
 
DECLARE
nValorDesconto NUMERIC(14,2);
nValorComissao NUMERIC(12,2);
 
BEGIN
    nValorDesconto := 0;
    nValorComissao := 0;
 
    IF nTipoDesconto = 0 THEN
        nValorDesconto := nDesconto;
    ELSE
        nValorDesconto := ( nTotal * nDesconto ) / 100;
    END IF;
 
    IF nTipoComissao = 0 THEN
        nValorComissao := nComissao;
    ELSE
        nValorComissao := ( nTotal * nComissao ) / 100;
    END IF;
 
    RETURN nTotal - nValorDesconto - nValorComissao;
END;
$$ LANGUAGE plpgsql
CALLED ON NULL INPUT
SECURITY INVOKER;
 
When i test this function, i call the function with this parameters :
 
SELECT CALCULO_VALOR_LIQUIDO_HELPDESK( 0, 1, 10, 10, 1000 );

 
This is the error that happens:
 
ERROR: function calculo_valor_liquido_helpdesk(integer, integer, integer,
integer, integer) does not exist
SQL state: 42883
Hint: No function matches the given name and argument types. You may need to
add explicit type casts.
 
I dont now what the two first parameters are see as integer. When 0 and 1
are true smallint values.
 
What is happeining here?
 
Thanks in advance.
