如何以编程方式更改标识列值？

import sqlite3

# 连接到数据库
conn = sqlite3.connect('example.db')

# 创建一个游标对象
cursor = conn.cursor()

# 更新标识列值
cursor.execute("UPDATE table_name SET column_name = new_value WHERE id = some_id")

# 提交更改
conn.commit()

# 关闭连接
conn.close()

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

public class Main {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/your_database";
        String user = "your_username";
        String password = "your_password";

        try {
            // 加载驱动程序
            Class.forName("com.mysql.jdbc.Driver");

            // 建立数据库连接
            Connection conn = DriverManager.getConnection(url, user, password);

            // 准备更新标识列值的SQL语句
            String sql = "UPDATE table_name SET column_name = ? WHERE id = ?";
            PreparedStatement pstmt = conn.prepareStatement(sql);

            // 设置参数
            pstmt.setString(1, "new_value");
            pstmt.setInt(2, some_id);

            // 执行更新
            pstmt.executeUpdate();

            // 关闭连接
            pstmt.close();
            conn.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
