JS读取mysql数据，易懂

代码：

var mysql  = require('mysql');
var connection = mysql.createConnection({
    host     : 'localhost',
    user     : 'root',
    password : 'password',
    port: '3306',
    database: 'nufix'
});
connection.connect();

var  sql = 'select * from dependency_info';
connection.query(sql,function (err, results) {
    if(err){
        console.log('[SELECT ERROR] - ',err.message);
        return;
    }

    if(results)
    {
        for(var i = 0; i < results.length; i++)
        {
            console.log("%d\t%s\t%s", i, results[i].project_name, results[i].dependency);
            break;
        }
    }
});
connection.end();
