nodejs和mysql交互问题

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 = 0i <results.lengthi++)

{

console.log("%d\t%s\t%s", results[i].id, results[i].name, results[i].age)

}

}

client.end()

}

)

3、运行结果

D:\nodejs\mysql>node mysql.js

1 u1 23

2 u2 24

3 u3 25
