Para evitar el uso de cursores se pueden crear tablas temporales con un campo identity. Despues se puede usar esta tabla temporal para recorrerla en un ciclo usando el identity para identificar el registro que se requiere. Un ejemplo de esto sería:
— Primero llenamos la tabla temporal (#x) nuestra consulta principal
select identity(int,1,1) as ID, Campos into #x from Tabla
— Preparamos las variables que nos ayudarán con el barrido.
declare @maximo int
declare @cont int
declare @Campos char(10)
set @maximo = (select max(ID) from #x)
set @cont =0
— Seguimos con el ciclo que generará el barrido.
While @cont <= @maximo
begin
set @cont=@cont+1
set @Campos = (select Campos from #x where [id] = @cont)
— Aquí se ponen las operaciones que sean necesarias.
end
— Listo!

If you want to obtain a publication on how to be able to engage in online casinos do not purchase
this kind of publication, since it is a report regarding Hellmuth’s profession and his or her major gain as well as online casinos pro buddies. Although it is a good place first off, I wouldn’t recommend
that you sit at the particular anchor spot and that is the very final seat.
