[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，制作各种测试脚本提供很好操作平台。DB-API:http://www.python.org/dev/peps/pep-0249/

注册License

eGenix.comCommercialLicenseAgreement1.2.0，注意填好后，Liscense会被发送到邮箱

Lincense拷贝的路径，本机地址：C:\Python25\Lib\site-packages\mx\ODBC

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：

class db2_test():

def truncate_table(self):

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。
