[Python-sybase-misc] TypeError: Unknown data format

[Andreas J. <li...@zo...>]

I installed Python 2.4.6 + python-sybase 0.3.9 compiled against FreeTSD
0.8.2 on a standard Linux box.

conn = connect(....)
cursor = conn.cursor()
cursor.execute('select "D_DID" from Dienstangaben')
for row in cursor.fetchall():
      print row

fails badly:

  File "test.py", line 5, in ?
    cursor.execute('select "D_DID" from Dienstangaben')
  File
"/root/python-sybase-0.39/lib/python2.4/site-packages/python_sybase-0.39-py2.4-linux-x86_64.egg/Sybase.py",

    row[col] = _column_value(buf[n], buf.datatype, outputmap)
TypeError: unknown data format

How to proceed?
