Hi, One small improvement.
Instead of execute statement :loc_sql into :out_fecha; I'd recommend for execute statement :loc_sql into :out_fecha do suspend; Reason: you can't be sure how many records :loc_sql will return, and if that's more than one, you'll end up with the 'multiple rows in singleton select' error. regards Tomasz W dniu 2011-11-07 14:04, Sergio pisze: > well... after doing my post I've found this.. > > http://www.firebirdfaq.org/faq322/ > > and I did this > > CREATE PROCEDURE PANIO_TERMINADO ( > in_id fk_id, > in_etapa codigo) > returns ( > out_fecha fecha_hora) > as > declare variable loc_sql descripcion; > begin > loc_sql = 'select ' || in_etapa || ' from pedidos_control where id = ' || > cast( :in_id as varchar(10)); > execute statement :loc_sql into :out_fecha; > suspend; > end > > It's OK? or it can be improved?
