[Zope] Sybase error: Products.SybaseDAv2.db.Error: ct_command():

(1) How do I check the transaction log? (I am a newbie to
    Sybase.)

(2) I am also getting another error. (I append the error message
    at the end of this posting.) I went into db.py file and
    printed out the value of f.datatype is 17 when it crashed.
    Does this help to trace the source of the bug? What else
    can I do to trace the bug? After the "invalid buffer element
    type" error, all hell breaks loose and Zope starts to
    issue more and more strange error messages.
