需要的准备工作:

下载

http://jaist.dl.sourceforge.net/sourceforge/zxjdbc/zxJDBC-2.1.tar.gz

http://jaist.dl.sourceforge.net/sourceforge/jython/jython_installer-2.2.1.jar

根据自己的jdk版本下载对应的ojdbc版本

http://download.oracle.com/otn/utilities_drivers/jdbc/10203/ojdbc14.jar

http://download.oracle.com/otn/utilities_drivers/jdbc/111060/lib/ojdbc5.jar

http://download.oracle.com/otn/utilities_drivers/jdbc/111060/lib/ojdbc6.jar

安装(需要已经安装了jdk/jre?)

java -jar jython_installer-2.2.1.jar 安装到C:\jython2.2.1

将zxJDBC.jar解压缩到c:\tmp

将mm.mysql-2.0.4-bin.jar复制到c:\tmp

C:\jython2.2.1>set CLASSPATH=c:\tmp\ojdbc5.jar;c:\tmp\zxJDBC.jar;%CLASSPATH%

启动Oracle服务器:

进入jython环境访问Oracle

编辑文件c:\tmp\ora.py

from oracle.jdbc.driver import OracleDriver

from java.sql import DriverManager

def connect(un, pw, sid, host, port):

driver = OracleDriver()

DriverManager.registerDriver(driver)

connection = "jdbc:oracle:thin:@%s:%s:%s" % (host, port, sid)

conn = DriverManager.getConnection(connection, un, pw)

return conn

def doStuff(conn):

stmt = conn.createStatement()

rset = stmt.executeQuery("SELECT banner FROM sys.v_$version")

while (rset.next()):

print rset.getString(1)

stmt.close()

if __name__ == "__main__":

un = 'ebc20'

pw = 'abc'

sid = 'abc'

host = '10.4.231.16'

port = '1521'

conn = connect(un, pw, sid, host, port)

doStuff(conn)

C:\jython2.2.1>jython \tmp\ora.py

Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi

PL/SQL Release 10.2.0.3.0 - Production

CORE 10.2.0.3.0 Production

TNS for HPUX: Version 10.2.0.3.0 - Production

NLSRTL Version 10.2.0.3.0 - Production

然后用jython自己封装的dbexts库。

最后编辑一个名为dbexts.ini的文件保存到c:\jython2.2.1\lib。

[default]

name=mysqltest

[jdbc]

name=ora

url=jdbc:oracle:thin:@10.4.231.16:1521:abc

user=ebc20

pwd=abc

driver=oracle.jdbc.driver.OracleDriver

datahandler=com.ziclix.python.sql.handler.OracleDataHandler

进入jython

>>> from dbexts import dbexts

>>> oracon = dbexts("ora", "c:\jython2.2.1\lib\dbexts.ini")

>>> oracon.isql("SELECT * FROM v$version")
