I don't know tutorials or examples, but you can use it simply like a
python dbi module.

First you need to setup DA and register it as a utility in
sitemanager, then you can get DA using by zapi.getUtility.

DA interface is very similar to python dbi module. I think zope3
becomes easier than zope2 to make rdb application.


from zope.app import zapi
from zope.app.rdb.interfaces import IZopeDatabaseAdapter
from zope.app.rdb import sqlquote
from zope.app.sqlscript.dtml import SQLDTML

class TableView:
    
    def cursor(self):
        da = zapi.getUtility(IZopeDatabaseAdapter, 'gadfly', self.context)
        con = da()
        return con.cursor()
    
    def getdata(self):
        cursor = self.cursor()
        cursor.execute('select name from mytable')
        return cursor.fetchall()
    
    def insertdata(self, name):
        cursor = self.cursor()
        template = SQLDTML('insert into mytable values(<dtml-sqlvar name 
type=string>)')
        cursor.execute(template(name=name))
        self.request.response.redirect('@@list.html')
