使用python连接到SQL Server 2008

Question

我正在尝试从python访问MS SQL服务器。

我安装了pymssql，这是我的代码

import pymssql

conn = pymssql.connect(host='SAM-WOLPTP\SAM', user='SAM', password='password', database='test')

cur = conn.cursor()
cur.execute('CREATE TABLE persons(id INT, name VARCHAR(100))')
cur.executemany("INSERT INTO persons VALUES(%d, %s)", \
[ (1, 'John Doe'), (2, 'Jane Doe') ])
conn.commit()  # you must call commit() to persist your data if you don't set autocommit to True

conn.close()

运行程序时出现此错误：

  

pymssql.InterfaceError：由于未知原因，与数据库的连接失败
