Netbeans binding

Netbeans binding

I'm trying to bind a table from my db in a Jtable in my desktop app. I had
follow the step in this guide:
https://netbeans.org/kb/docs/java/gui-binding.html and everything is fine,
but I can't change the query to show the data in a different order. If I
try to change the query the application does not work. Netbeans had create
the query so:
SELECT t FROM TbAzioni t
my table name is tb_azioni and I would like to have a query like this:
select * from tb_azioni order by azcodaz
but if I change the query nothing works. Thank you
