You can do it this way:

var values = [
  { users: "tom", id: 101 },
  { users: "george", id: 102 }
];
var queries = '';

values.forEach(function (item) {
  queries += mysql.format("UPDATE tabletest SET users = ? WHERE id = ?; ", item);
});

connection.query(queries, defered.makeNodeResolver());

To use multiple statements feature you have to enable it for your connection:

var connection = mysql.createConnection({
  ...
  multipleStatements: true,
});
