NodeJS与Mysql的交互

把Mysql Module装到NodeJS中
Js代码

$npm install Mysql

　 JS脚本 mysqlTest.js

Js代码
// mysqlTest.js

//加载mysql Module

var Client = require('mysql').Client,

client = new Client(),

　　

　 //要创建的数据库名

TEST_DATABASE = 'nodejs_mysql_test',

//要创建的表名

TEST_TABLE = 'test';



//用户名

client.user = 'root';

//密码

client.password = 'root';

//创建连接

client.connect();



client.query('CREATE DATABASE '+TEST_DATABASE, function(err) {

if (err && err.number != Client.ERROR_DB_CREATE_EXISTS) {

throw err;

}

});



// If no callback is provided, any errors will be emitted as `'error'`

// events by the client

client.query('USE '+TEST_DATABASE);

client.query(

'CREATE TABLE '+TEST_TABLE+

'(id INT(11) AUTO_INCREMENT, '+

'title VARCHAR(255), '+

'text TEXT, '+

'created DATETIME, '+

'PRIMARY KEY (id))'

);



client.query(

'INSERT INTO '+TEST_TABLE+' '+

'SET title = ?, text = ?, created = ?',

['super cool', 'this is a nice text', '2010-08-16 10:00:23']

);



var query = client.query(

'INSERT INTO '+TEST_TABLE+' '+

'SET title = ?, text = ?, created = ?',

['another entry', 'because 2 entries make a better test', '2010-08-16 12:42:15']

);



client.query(

'SELECT * FROM '+TEST_TABLE,

function selectCb(err, results, fields) {

if (err) {

throw err;

}



console.log(results);

console.log(fields);

client.end();

}

);
