因为两个都是基于 DB-API 2.0 标准,使用上差别并不大,区别就是 mysql-connector-python 是由 Oracle 官方提供,性能可能会好一些。 安装依赖 pip install mysql-connector-python 事务(update) importmysql.connector# 连接到MySQL数据库config = {'user':'root','password':'root','host':'127.0.0.1','d...
准备一个SQL语句,这里以插入数据为例。 # 定义准备好的SQL语句prepared_statement="INSERT INTO users (name, age) VALUES (%s, %s)" 1. 2. 使用占位符%s来表示将要插入的参数。 3. 执行预处理语句 在Python中,我们会使用cursor来执行SQL命令。 # 创建游标cursor=connection.cursor()# 准备SQL语句cursor.prep...
在上面的类图中,Cursor类表示游标对象,其中的prepare()方法用于预编译SQL语句,execute()方法用于执行预编译的SQL语句,fetchall()方法用于获取查询结果,close()方法用于关闭游标。PreStatement类表示预编译的SQL语句对象,其中的execute()方法用于执行预编译的SQL语句,传入参数。 总结 本文介绍了Python中如何使用MySQL Conne...
