you definitely don't want to add presentation information to SQL calls and
it's pretty much impossible with SQL-methods which contain by and large
You can write a PythonScript or an ExternalMethod to do what you want but I
can't see a good reason for it. You'd then have to "render" these scripts
specially in your PageTemplates. It is much better in my opinion to do your
presentation in your ZPT where you and others have full control over it.
You can still make presentation dependent on the type of data you receive.
