nodejs中操作mysql數(shù)據(jù)庫示例_node.js

內(nèi)容： 下面這個所演示的是NodeJS與Mysql 的交互。

這時需要為NodeJS加入Mysql 的Module了，這時前一章說到的npm（Node package manager）啟到作用了。

把Mysql Module裝到NodeJS中：

代碼如下:
$npm install Mysql

JS腳本 mysqlTest.js
代碼如下:
// mysqlTest.js
//加載mysql Module
var Client = require(‘mysql').Client,
client = new Client(),

//要創(chuàng)建的數(shù)據(jù)庫名
TEST_DATABASE = ‘nodejs_mysql_test',
//要創(chuàng)建的表名
TEST_TABLE = ‘test';

//用戶名
client.user = ‘root';
//密碼
client.password = ‘root';
//創(chuàng)建連接
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();
}
);

執(zhí)行腳本
代碼如下:
node mysqlTest.js

效果如下:
