pymssql 安装和使用

Windows环境

安装环境：python 2.7 + Eclipse 4.3 + pydev 3.9 + pymssql 2.01
注意：
64位Eclipse必须使用64位JDK，32位Eclipse必须使用32位JDK



1. 下载 pydev
http://sourceforge.net/projects/pydev/files/pydev/
注意： pydev 3.9必须使用java 7及以上版本，否则Eclipse无反应

2. 下载 pymssql-2.0.1.win32-py2.7.exe
https://pypi.python.org/pypi/pymssql/2.1.0
执行exe文件，python 安装目录下会出现_mssql.pyd 和 pymssql.pyd
C:\Python27\Lib\site-packages

3.测试

from pymssql import connect  # @UnresolvedImport

conn = connect(host="127.0.0.1", user="DataClient", password="test", 
               database="TimeSeries")
cursor = conn.cursor()
cursor.execute("exec getResearchSalesAndRepurchaseByYear %s, %d", ('F000000I1F',2011))
rows = cursor.fetchall()

for row in rows:
    print row[0]
    print row[1]
    
# cursor.execute("""
# IF OBJECT_ID('persons', 'U') IS NOT NULL
#     DROP TABLE persons
# CREATE TABLE persons (
#     id INT NOT NULL,
#     name VARCHAR(100),
#     salesrep VARCHAR(100),
#     PRIMARY KEY(id)
# )
# """)

# cursor.executemany(
#     "INSERT INTO persons VALUES (%d, %s, %s)",
#     [(1, 'John Smith', 'John Doe'),
#      (2, 'Jane Doe', 'Joe Dog'),
#      (3, 'Mike T.', 'Sarah H.')])
# # you must call commit() to persist your data if you don't set autocommit to True
# conn.commit()

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

conn.close()

在"from pymssql import connect"会提示错误：“unresolved import connect”, 这是静态代码检查报错。 解决方法，将鼠标放在报错的行，按“ctrl+1” 选择“unresolvedimport”, 会自动加入注释“# @UnresolvedImport”。
