如何在python中使用sqlite3登录到Oracle数据库

import sqlite3
import cx_Oracle

conn = sqlite3.connect('sqlite.db')
cursor = conn.cursor()

oracle_conn = cx_Oracle.connect('username/password@host:port/service_name')
oracle_cursor = oracle_conn.cursor()

cursor.execute('SELECT * FROM table_name')

result = cursor.fetchall()

cursor.close()
conn.close()
oracle_cursor.close()
oracle_conn.close()

import sqlite3
import cx_Oracle

# 连接SQLite数据库
conn = sqlite3.connect('sqlite.db')
cursor = conn.cursor()

# 连接Oracle数据库
oracle_conn = cx_Oracle.connect('username/password@host:port/service_name')
oracle_cursor = oracle_conn.cursor()

# 执行查询语句
cursor.execute('SELECT * FROM table_name')

# 获取查询结果
result = cursor.fetchall()

# 关闭游标和连接
cursor.close()
conn.close()
oracle_cursor.close()
oracle_conn.close()
