1 首先,安装第三方库 cx_Oracle
2 其次,配置命令
python
import cx_Oracle
# 1.数据库连接的基本信息
user = 'scott'
password = 'scott'
host = '127.0.0.1:1521'
service_name = 'orcl'
connect_str = f'{user}/{password}@{host}/{service_name}' # 格式化
# 2.通过 cx_Oracle 模板连接 Oracle 数据库
connect = cx_Oracle.connect(connect_str)
print(f'连接信息:{connect}')
# 3.通过游标 cursor 执行 sql
cursor = connect.cursor()
cursor.execute('select * from scott.dept')
for i in cursor.fetchall():
print(i)
执行结果:
sql
连接信息:<cx_Oracle.Connection to scott@127.0.0.1:1521/orcl>
