講解jython訪問Oracle數據庫的具體步驟

需要的准備工作： 下載 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 根據自己的jdk版本下載對應的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 安裝（需要已經安裝了jdk/jre?） java -jar jython_installer-2.2.1.jar 安裝到C:\jython2.2.1 將zxJDBC.jar解壓縮到c:\tmp 將mm.mysql-2.0.4-bin.jar複制到c:\tmp C:\jython2.2.1>set CLASSPATH=c:\tmp\ojdbc5.jar;c:\tmp\zxJDBC.jar;%CLASSPATH% 啓動Oracle服務器: 進入jython環境訪問Oracle 編輯文件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_$version") while (rset.next()): print rset.getString(1) stmt.close() if __name__ == "__main__": un = 'ebc20' pw = 'abc' sid = 'abc' host = '10.4.231.16' port = '1521' conn = connect(un, pw, sid, host, port) doStuff(conn) C:\jython2.2.1>jython \tmp\ora.py Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi PL/SQL Release 10.2.0.3.0 - Production CORE 10.2.0.3.0 Production TNS for HPUX: Version 10.2.0.3.0 - Production NLSRTL Version 10.2.0.3.0 - Production 然後用jython自己封裝的dbexts庫。 最後編輯一個名爲dbexts.ini的文件保存到c:\jython2.2.1\lib。 [default] name=mysqltest [jdbc] name=ora url=jdbc:oracle:thin:@10.4.231.16:1521:abc user=ebc20 pwd=abc driver=oracle.jdbc.driver.OracleDriver datahandler=com.ziclix.python.sql.handler.OracleDataHandler 進入jython >>> from dbexts import dbexts >>> oracon = dbexts("ora", "c:\jython2.2.1\lib\dbexts.ini") >>> oracon.isql("SELECT * FROM v$version") BANNER ---------------------------------------------------------------- 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 5 rows affected
