How do I do a bulk insert in mySQL using node.js

Source: https://stackoverflow.com/questions/8899802/how-do-i-do-a-bulk-insert-in-mysql-using-node-js

Bulk inserts are possible by using nested array, see the github page

Nested arrays are turned into grouped lists (for bulk inserts), e.g. [['a', 'b'], ['c', 'd']] turns into ('a', 'b'), ('c', 'd')

You just insert a nested array of elements.

An example is given in here

var mysql = require('node-mysql');
var conn = mysql.createConnection({
    ...
});

var sql = "INSERT INTO Test (name, email, n) VALUES ?";
var values = [
    ['demian', 'demian@gmail.com', 1],
    ['john', 'john@gmail.com', 2],
    ['mark', 'mark@gmail.com', 3],
    ['pete', 'pete@gmail.com', 4]
];
conn.query(sql, [values], function(err) {
    if (err) throw err;
    conn.end();
});

Note: values is an array of arrays wrapped in an array

[ [ [...], [...], [...] ] ]
