使用python访问Oracle数据库

import cx_Oracle

import os



if False:  #当Oracle服务是手动运行时，将False改为True

	os.system('net start OracleVssWriterORCL')

	os.system('net start OracleDBConsoleorcl')

	os.system('net start OracleOraDb11g_home1TNSListener')

	os.system('net start OracleServiceORCL')



orcl = cx_Oracle.connect('system/username@localhost:1521/orcl'.decode('utf8'))

cur = orcl.cursor()



sql = '''select * from test1

		'''

cur.execute(sql.decode('utf8'))

records = cur.fetchall()

lines = len(records)

for i in range(lines):

	print records[i]

cur.close()
