RRrrrriiiiigggghhhttt.... that said.... I just tried again... and now
have a fail. Now I also remember why I didn't use that method yet :)

- Debian Sarge, MySQLdb 1.2.1g2: works fine.
- Mandriva Linux LE2005 (v10.2), MySQLdb 1.2.1g3: gives SQL error on
this one.

>>> cursor.execute("INSERT INTO testtable (field1) VALUES ('This is a
>>> cursor.execute("INSERT INTO testtable (field1) VALUES (%s);"% s)

Traceback (most recent call last):
  File "<pyshell#15>", line 1, in -toplevel-
    cursor.execute("INSERT INTO testtable (field1) VALUES (%s);"% s)
  File "/usr/lib/python2.4/site-packages/MySQLdb/cursors.py", line 137,
in execute
    self.errorhandler(self, exc, value)
  File "/usr/lib/python2.4/site-packages/MySQLdb/connections.py", line
33, in defaulterrorhandler
    raise errorclass, errorvalue
ProgrammingError: (1064, 'You have an error in your SQL syntax; check
the manual that corresponds to your MySQL server version for the right
syntax to use near \'\'some\' stuff with "quotes" and stuff)\' at line

- Mandriva Linux 2006.0, MySQLdb 1.2.0final: works fine.

So there is a serious bug in MySQLdb as well; seems to be the 1.2.1g3
