Hi All,
This is my first post to any mailing group. I am QA engg and
using python for testing automation. I need to connect with Mysql
(2008) and mssql databases for executing some queries.
I have installed following modules & softwares in python 2.7 :
python 2.7.2
setuptools
MySQLdb Module
pymssql module
yum install mysql msql-devel freetdf
I have installed freetds 0.9version. After installation of all the above
components, I have done following things
Python 2.6 (r26:66714, Apr 8 2010, 08:46:35)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymssql
>>> conn = pymssql.connect(host='mssql_server', user='_username',
password='_password', database='_db',as_dict=True)
>>> cur = conn.cursor()
>>> cur.execute('select count(*) from D2.dbo.abc (nolock)')
>>> print cur.fetchall()
[]
>>> cur.rowcount
-1
>>> exit()
I am expecting that the result of the query will be 16. But it is not
retuning any data from query with no error at any place. On execting the
same query in tsql, I got result as 16.
