Checking specific error codes from within Zope is a PITA because of access control on 
the Exception object.

You'll need to modify gvibExceptions.py, add doc strings to     def getSqlCode(self) 
other methods.. And probably add


hack lines to Exception class defs.

OTH, if you use an external method to process the gvib request, or create an external 
method that can extract the sqlCode for you.. then you wouldn't need these mods.

def getSqlCode(exceptionObject):
    """Return the sqlcode"""
    return exceptionObject.getSqlCode()

Then when you get an exception, pass the exception object to the external method to 
get the sqlcode.
