Ich würde ein Array von Objekten versuchen
[
{name:'Hy Dag3', points:'55040464', rank:'master', hotStreak:114,...},
{name:'Hkj', points:'554064', rank:'novice', hotStreak:14,...}
]
und dann
this.conn.query("INSERT summoners SET ? " +
" ON DUPLICATE KEY UPDATE name = VALUES(name), rank = VALUES(rank)...
Denn laut doc:
var post = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function (error, results, fields) {
if (error) throw error;
// Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
