Here is a real-life example of class created dynamically from SQL (cut
just to relevant fragments).

  from Acquisition import Implicit
  from AccessControl import ClassSecurityInfo
  from Globals import InitializeClass
  
  class theBasket(Implicit):
      """The basket"""
  
      id=meta_type = "Basket"
      title = "The basket"
  
      security = ClassSecurityInfo()
      security.declareObjectPublic()
      security.setDefaultAccess("allow")
  
      def __init__(self, id):
          ...
  
      ...
  
  InitializeClass(theBasket)

  class BasketGenerator(Something):
      """Basket Generator product kept in ZODB"""
      def __getitem__(self, id):
          """Return theBasket instance"""
          rv = theBasket(self, id)
          return rv.__of__(self)
  

Works just fine, including security declarations and acquisition.
