[Zope] Howto convert ZSQL results

[Julián Muñoz Domínguez]

Thanks a lot !!!

The query I am doing is:
select MAX(CliCodigo) from ClientesTabla

And the column that is returned by zope is named 'Expr1000' (a bit
strange :-)), and doing:

 I=int(container.last_customer()[0].Expr1000)

Works !!!
Thank you, I was becoming fool :-)
