React Native从Mysql DB获取新数据

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'password',
  database: 'mydatabase',
});

connection.connect((err) => {
  if (err) {
    console.error('Error connecting to Mysql DB: ', err);
    return;
  }
  console.log('Connected to Mysql DB');
});

connection.query('SELECT * FROM mytable', (err, results) => {
  if (err) {
    console.error('Error executing query: ', err);
    return;
  }
  console.log('Fetched new data from Mysql DB: ', results);
});

connection.query('SELECT * FROM mytable', (err, results) => {
  if (err) {
    console.error('Error executing query: ', err);
    return;
  }
  // 处理查询结果
  // 更新React Native应用的状态或渲染新的数据
});
