I am running the code in the tutorial part of node-mysql and its giving me error
**Code**
var MySQLPool = require("mysql-pool").MySQLPool;
var pool = new MySQLPool({
poolSize: 4,
user: 'root',
password: 'root',
database: 'test'
});
pool.query("SELECT 'Hello, World!' AS hello", function(err, rows, fields) {
if(err) throw err;
console.log(rows[0].hello);
});
for(var i = 0; i < 10; ++i) {
pool.query("SELECT SLEEP(2), ? AS i", [i], function(err, rows, fields) {
if(err) throw err;
console.log("Slept: " + rows[0].i);
});
}
