Description of problem:
Using code from the pymssql user guide fails when a string parameter binding is involved.

Version-Release number of selected component (if applicable):
0.8.0-2.el5

How reproducible: 100%

Steps to Reproduce:
Create a database table like this:
CREATE TABLE persons(id INT,fullname VARCHAR(200))

Now, try running code like this:
#=====================================================================
#!/usr/bin/env python

import pymssql

conn = pymssql.connect(host='h', user='u', password='p',database='d')
cur = conn.cursor()
cur.execute('INSERT INTO persons VALUES(%d, %s)',(5,'John Doe'))
conn.commit()

cur.execute('SELECT * FROM persons WHERE fullname=%s','John Doe')
row = cur.fetchone()
while row:
    print "ID=%d, Name=%s" % (row[0], row[1])
    row = cur.fetchone()

conn.close()
#=====================================================================
 
Actual results:
The script returns an error:
Traceback (most recent call last):
  File "./pymssql-test.py", line 11, in ?
    cur.execute('SELECT * FROM persons WHERE fullname=%s','John Doe')
  File "/usr/lib64/python2.4/site-packages/pymssql.py", line 126, in execute
    self.executemany(operation, (params,))
  File "/usr/lib64/python2.4/site-packages/pymssql.py", line 152, in executemany
    raise DatabaseError, "internal error: %s" % self.__source.errmsg()
pymssql.DatabaseError: internal error: None

Expected results:
ID=5, Name=John Doe

Additional info:
I tried recompiling the package using the latest upstream version (1.0.1), and now things work as expected. The recompilation was very straight forward, except that the spec file's %doc-line needed to be changed to this:
%doc README ChangeLog TODO lgpl.txt

By the way, the description of the package starts with this sentence:
   An "almost" DB-API 2.0 compliant module for access 
   to Microsoft SQL servers from Python.
The project page at http://pymssql.sourceforge.net/ doesn't mention any non-compliance. Maybe the description needs to be changed, if the latest source code (1.0.1) for the package is used.
