[数据库测试]强烈推荐一个python ODBC数据源插件，可支持Oracle，Db2，Mysql，Sql-server以及各种数据库版本，附例子和测试程序

今天有很多时间，再与大家分享一个最近使用的到第三方控件，个人认为对设计一些数据库测试脚本非常有用。

首先，请访问这个地址：http://www.egenix.com/products/python/mxODBC/，此控件是一个ODBC的通用插件。

这为我们通过Windows系统，***各种测试脚本提供很好操作平台。DB-API:http://www.python.org/dev/peps/pep-0249/

如果没有注册Liscense，会有如下提示：

以下提供一段测试程序，该段程序为清除Db2中的两表数据：


# -*- coding: cp936 -*-


import mx.ODBC


import mx.ODBC.Windows




IDLE中提示：


Traceback (most recent call last):


File "E: tpSearch_Table.py", line 3, in <module>


import mx.ODBC.Windows


File "mxODBCWindows__init__.py", line 9, in <module>


ImportError: initialization of module mxODBC failed (<class 'mx.ODBC.Windows.LicenseError'>:mx.ODBC.license could not be loaded; please visit the http://www.egenix.com/ web-site to obtain a license file or write to licenses@egenix.com for information.)




提取有效部分：license could not be loaded; please visit the http://www.egenix.com/ web-site to obtain a license file or write to licenses@egenix.com for information




# -*- coding: cp936 -*-


import mx.ODBC


import mx.ODBC.Windows


import sys, os ,time




class db2_test():




def __init__(self, tablename1, tablename2):


self.tablename1 = tablename1


self.tablename2 = tablename2


print self.tablename1, self.tablename2





#清除任意制定表数据


def truncate_table(self):


db = mx.ODBC.Windows.DriverConnect( 'DSN=infospy' )


cursor = db.cursor()


cursor.execute("ALTER TABLE %s ACTIVATE NOT LOGGED INITiALLY WITH EMPTY TABLE;" % (self.tablename1))


cursor.execute("ALTER TABLE %s ACTIVATE NOT LOGGED INITiALLY WITH EMPTY TABLE;" % (self.tablename2))


cursor.execute("Commit;")


cursor.close()


db.close()


print "表%s;%s; 清除数据成功！" % (self.tablename1, self.tablename2)





if __name__ == "__main__":


tablename1 = "test_table_1"


tablename2 = "test_table_2"


db2 = db2_test(tablename1, tablename2)


db2.truncate_table()


time.sleep(3)


sys.exit(1)

db = mx.ODBC.Windows.DriverConnect( 'DSN=infospy' ) DSN为在WindowsODBC中配置的数据源名

有关ODBC配置，此贴略。由于时间关系，详细的API请查询文章中所给的地址。
