您可以跳过ORM，构建器等，并使用sqler和sqler-mdb简化您的DB/SQL管理。

WHERE UPPER(TST.NAME) LIKE CONCAT(CONCAT('%', UPPER(:name)), '%')

    "db": {
      "mdb": {
        "host": "localhost",

        }
      }
    ]
  }
};

// create/initialize manager
const manager = new Manager(conf);
await manager.init();

// .sql file path is path to db function
const result = await manager.db.mdb.read.table.rows({
  binds: {
    name: 'Some Name'
  }
});

console.log('Result:', result);

// after we're done using the manager we should close it
process.on('SIGINT', async function sigintDB() {
  await manager.close();
  console.log('Manager has been closed');
});

降级可能不是一个好的选择，因为:

它升级是有原因的(为了提供更好的身份验证)。 您可能没有足够的权限来进行此类更改。

你可以使用mysql2包来代替mysql。它的大部分API与mysqljs兼容。 此外，它有承诺支持。

像这样使用它: Const mysql = require('mysql2/promise')(用于基于promise的方法)

你可以在这里阅读更多关于mysql2的内容:https://www.npmjs.com/package/mysql2

在MYSQL Workbench中执行以下查询

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password

root用户在哪里 localhost作为URL 密码就是你的密码

然后运行这个查询刷新特权:

冲洗特权;

在执行此操作后尝试使用node进行连接。

如果不工作，尝试没有@'localhost'部分。

如果你有权限创建一个新的用户权限，然后这样做，以正常连接node.js，这对我来说是有效的

您可以在这里找到原始文档:https://dev.mysql.com/doc/dev/connector-nodejs/8.0/

'use strict';

const mysqlx = require('@mysql/xdevapi');

const options = {
  host: 'localhost',
  port: 33060,
  password: '******',
  user: 'root',
  schema: 'yourconference'
};

mysqlx.getSession(options)
  .then(session => {
          console.log(session.inspect());
           session.close();
  }).catch(err => {
    console.error(err.stack);
    process.exit(1);
  });
