Обсуждение: Set returning functions and Crystal Reports

Hello list,

Apologize first if this is off topic.

have this function in plpgsql

DECLARE
    crow histmer%rowtype;
BEGIN
    select * into crow from histmer
    where fecha = date 'now';
    if found then
        return next crow;
    end if;
    select * into crow from histmer order by fecha desc limit 1 ;
    insert into histmer values (date 'now', crow.mercado_ne, crow.factor_adu) ;
    select * into crow from histmer
        where fecha = date 'now';

return;
END

Any idea to make Crystal Reports (10) to accept it as a data set resulting?

Thanks in advace
