Re: VARCHAR values are always the length of the field

[Edson Carlos Ericksson Richter]

I think that all are crazy... I have one wizard in my company that create
persistent classes that are so easy, not
"deploy-then-copy-to-here-then-change-then-copy-to-there-then-deploy"!!!

Why not Application Deployment Wizard does not ask for what datasource we
want to use, what table name, and presents some type of window to do the O-R
mapping (using dbschema as defaults, for ones that want to use defaults)?
