mysql2 async/await未定义的行和字段node.js

为什么下面的查询返回未定义的行和字段，即使用户表有数据？如何在typescript中正确使用promise版本。任何帮助都将不胜感激。谢谢你

代码

控制台输出

未定义未定义

成功连接到数据库

查看mysql，我有两个建议：

• 我发现您需要更改正在导入的内容
• 您还需要等待

  createConnection

  调用

import mysql from 'mysql2';
import 'dotenv/config';
import bluebird from 'bluebird';

//? this all configuration for database connection
const connection: any = mysql.createConnection({
  host: process.env.DB_HOSTNAME,
  user: process.env.DB_USER,
  database: process.env.DATABASE,
  Promise: bluebird,
});

//! test connection - required
const testConnection = async () => {
  try {
    //? output to the console the query value
    let [rows, fields]: [any, any] = await connection.execute(
      'SELECT * FROM user',
    );
    console.log(rows, fields);
    console.log('successfully connected to database');
  } catch (error) {
    console.log(error);
  }
};


testConnection();

// get the client
const mysql = require('mysql2/promise');

// get the promise implementation, we will use bluebird
const bluebird = require('bluebird');

// create the connection, specify bluebird as Promise
const connection = await mysql.createConnection({host:'localhost', user: 'root', database: 'test', Promise: bluebird});

// query database
const [rows, fields] = await connection.execute('SELECT * FROM `table` WHERE `name` = ? AND `age` > ?', ['Morty', 14]);
