Hello! I see you are a first-time contributor, thank you for taking the time to help Sequelize! I hope to see more PRs from you in the future!

Tests are failing though, please take a look :)

Also your branch was outdated, I just brought it up to date for you (don't worry about this):

Let me know if you need help. Thanks!!

Great, I like your tests, and tests are passing, so LGTM!

I'm having this problem:

const theCode = '10$off';
PromoCodes.findAll({
  where: {
    code: sequelize.where(sequelize.fn('lower', sequelize.col('code')), sequelize.fn('lower', theCode))
  }
});

This never finds it because it does lower("code") = lower('10$$off'). Solution was to do theCode.toLowerCase(), but this is still a bug.
