node-mysql -一个实现MySQL协议的node.js模块 node-mysql2 -另一个纯JS异步驱动程序。流水线，准备好的语句。 node-mysql-libmysqlclient -基于libmysqlclient的MySQL异步绑定

Node-mysql看起来很简单:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'example.org',
  user     : 'bob',
  password : 'secret',
});

connection.connect(function(err) {
  // connected! (unless `err` is set)
});

查询:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

node-mysql可能是用于MySQL数据库的最好的模块之一，它是积极维护和良好的文档。

通过安装库连接mysql数据库。在这里，选择了稳定且易于使用的node-mysql模块。

npm install mysql@2.0.0-alpha2

var http = require('http'),
   mysql = require('mysql');

var sqlInfo = {
   host: 'localhost',
   user: 'root',
   password: 'urpass',
   database: 'dbname'
}
client = mysql.createConnection(sqlInfo);

client.connect();

用于NodeJS mysql连接和查询的例子

KnexJs可以在Node.JS和浏览器中用作SQL查询构建器。 我发现它很容易使用。让我们试试它- Knex.js

$ npm install knex --save
# Then add one of the following (adding a --save) flag:
$ npm install pg
$ npm install sqlite3
$ npm install mysql
$ npm install mysql2
$ npm install mariasql
$ npm install strong-oracle
$ npm install oracle
$ npm install mssql


var knex = require('knex')({
  client: 'mysql',
  connection: {
    host : '127.0.0.1',
    user : 'your_database_user',
    password : 'your_database_password',
    database : 'myapp_test'
  }
});

你可以这样用

knex.select('*').from('users')

or

knex('users').where({
  first_name: 'Test',
  last_name:  'User'
}).select('id')

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。

-- create this file at: db/mdb/setup/create.database.sql
CREATE DATABASE IF NOT EXISTS sqlermysql

const conf = {
  "univ": {
    "db": {
      "mdb": {
        "host": "localhost",
        "username":"admin",
        "password": "mysqlpassword"
      }
    }
  },
  "db": {
    "dialects": {
      "mdb": "sqler-mdb"
    },
    "connections": [
      {
        "id": "mdb",
        "name": "mdb",
        "dir": "db/mdb",
        "service": "MySQL",
        "dialect": "mdb",
        "pool": {},
        "driverOptions": {
          "connection": {
            "multipleStatements": true
          }
        }
      }
    ]
  }
};

// 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.setup.create.database();

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');
});
