give me insert codes

在数据库中插入数据通常涉及到 SQL（Structured Query Language）命令，这里是一个基本的示例，假设我们有一个名为 `users` 的表，包含 `id`, `name`, 和 `email` 字段：

-- 使用 MySQL 数据库为例
INSERT INTO users (id, name, email)
VALUES (1, '张三', 'zhangsan@example.com');

-- 使用 Python 和 sqlite3 库操作SQLite数据库
import sqlite3

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

# 插入数据
cursor.execute("INSERT INTO users (id, name, email) VALUES (?, ?, ?)", 
              (1, '李四', 'lisi@example.com'))

# 提交事务并关闭连接
conn.commit()
conn.close()

在这个例子中，第一行是直接在 SQL 查询中插入了一条记录。第二部分展示了如何在 Python 中使用 SQLite3 来执行同样的插入操作。
