在PYTHON中，用cx_Oracle连接ORACLE数据库简单示例

python setup.py build install

#dsn = orcl.makedsn(self.oracle_host, self.oracle_port, self.oracle_sid)
#con = orcl.connect(self.oracle_username, self.oracle_password, dsn)
con = orcl.connect(self.oracle_username,self.oracle_password,self.oracle_alarm_ciname)
cursor = con.cursor()
sql = "select '%s'  from dual" % (test_str,)
cursor.execute(sql);
result = cursor.fetchall()
cursor.close()
con.close()

select 'OK'  from dual
