create database

await client.execute(`CREATE DATABASE IF NOT EXISTS enok`);
await client.execute(`USE enok`);

await client.execute(`
    CREATE TABLE users (
        id int(11) NOT NULL AUTO_INCREMENT,
        name varchar(100) NOT NULL,
        created_at timestamp not null default current_timestamp,

  "manyuanrong"
]);
console.log(result);
// { affectedRows: 1, lastInsertId: 1 }

// { affectedRows: 1, lastInsertId: 0 }

query

const username = "manyuanrong";
const users = await client.query(

const queryWithParams = await client.query(
  "select ??,name from ?? where id = ?",
  ["id", "users", 1]
