nodeJs鏈接Mysql，做增刪改查

nodejs連接Mysql，首先安裝了mysql之後，在cmd界面安裝nodeJs的mysql模塊：
npm install mysql

mysql中創建數據庫“nodetry1”，再創建表table2:

指定id爲主鍵：

var mysql = require('mysql');

//選擇數據庫和表
var TEST_DATABASE = 'nodetry1';
var TEST_TABLE = 'table2';

var connection = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: '123456'
});

//連接數據庫
connection.connect();

//選擇查詢的數據庫
connection.query("use " + TEST_DATABASE);

// 增加
connection.query('insert into '+ TEST_TABLE +' (id,name,age) values (12, "二次添加會報錯" , 77)');

// 刪除
connection.query('delete from '+ TEST_TABLE +' where name = "sony"');

// 修改
connection.query('update '+ TEST_TABLE +' set name = "jiying.bao" where id = 5');

//查詢
connection.query('SELECT * from '+ TEST_TABLE , function(err, rows) {
    if(err) throw err;
    console.log("SELECT ==> ");
    for(var i in rows) {
        console.log(rows[i]);
    }
});

//關閉數據庫連接
connection.end();
