python连接oracle数据库的新模块
从原来的cx_Oralce更新为oracldb
cx_Oracle has a major new release under a new name and homepagepython-oracledb.
New projects should install python-oracledb instead of cx_Oracle.

使用方法：
import oracledb

You must replace positional parameters with keyword parameters, unlessonly one parameter is being passed. Python-oracledb uses keyword parametersexclusively unless a DSN containing the user, password, and connect stringcombined, for example un/pw@cs, is used. This change makes the drivercompliant with the Python Database API specification PEP 249.
For example, the following code will fail:
c = oracledb.connect("un", "pw", "cs")

and needs to be changed to:
c = oracledb.connect(user="un", password="pw", dsn="cs")

The following example will continue to work without change:
c = oracledb.connect("un/pw@cs")

eg：
c=oracledb.connect('user/pwd@192.168.1.1:1521/your_db_name')
