(no subject)

using code:

import Sybase
try:
        s = Sybase.connect('Oscar', 'docent', 'docent')
        cur = s.cursor()
        cur.execute("select * from docent.DRUser where lastName = 'Glassel'")
        print cur.description
        for tup in cur.description:
                print tup[0],
        print
        while 1:
                rec = cur.fetchall()
                if not rec: break
                print rec
except NameError,e:
        print 'error ', e, 'undefined'


i get this error:

Traceback (most recent call last):
  File "one.py", line 11, in ?
    rec = cur.fetchall()
  File "/usr/lib/python2.2/site-packages/Sybase.py", line 489, in fetchall
    row = self.fetchone()
  File "/usr/lib/python2.2/site-packages/Sybase.py", line 413, in fetchone
    _array = _fetch_rows(self._cmd, self._bufs)
  File "/usr/lib/python2.2/site-packages/Sybase.py", line 199, in _fetch_rows
    raise Error('ct_fetch')
Sybase.Error: ct_fetch


the description part works, why can't I print the record??

-regards
