Nodejs连接mysql数据库

//1、首先需要安装nodejs 的mysql包
npm install mysql

//2、编写nodejs与mysql交互的代码
var mysql = require('mysql');  
var TEST_DATABASE = 'ceshi';  
var TEST_TABLE = 'user';  
  
//创建连接  
var client = mysql.createConnection({  
	user: 'root',  
	password: ''  
});  

client.connect();
client.query("use " + TEST_DATABASE);

client.query(  
	'SELECT * FROM '+TEST_TABLE,  
	function selectCb(err, results, fields) {  
	if (err) {  
		throw err;  
	};
	if(results)
		{
			for(var i = 0; i < results.length; i++)
			{
				console.log("%d\t%s\t%s", results[i].id, results[i].name, results[i].age);
			}
		}    
	client.end();  
	};
);
