All props to Ragnar123 for his answer.

I just wanted to expand it after the question asked by Josh Harington to talk about inserted IDs.

These will be sequential. See this answer : Does a MySQL multi-row insert grab sequential autoincrement IDs?

Hence you can just do this (notice what I did with the result.insertId):

  var statement = 'INSERT INTO ?? (' + sKeys.join() + ') VALUES ?';
  var insertStatement = [tableName, values];
  var sql = db.connection.format(statement, insertStatement);
  db.connection.query(sql, function(err, result) {
    if (err) {
      return clb(err);
    }
    var rowIds = [];
    for (var i = result.insertId; i < result.insertId + result.affectedRows; i++) {
      rowIds.push(i);
    }
    for (var i in persistentObjects) {
      var persistentObject = persistentObjects[i];
      persistentObject[persistentObject.idAttributeName()] = rowIds[i];
    }
    clb(null, persistentObjects);
  });

(I pulled the values from an array of objects that I called persistentObjects.)

Hope this helps.
