Laravel: Pass Parameter to Relationship Function?

Is it possible to pass, somehow, a parameter to a relationship function? I have currently the following: public function achievements() { return $this->belongsToMany('Achievable', 'user_achievements')->withPivot('value', 'unlocked_at')->orderBy('pivot_unlocked_at', 'desc'); } The problem is that, in some cases, it does not fetch the unlocked_at column and it returns an error.

is MySql good for large databases?

I work for a company and we are always accessing an external site for information. The site was developed by an antiquated software development company who doesn't even have a website. They pretty much have a monopoly in my state since the content provider for the database only uses this extremely dysfunctional site to upload their data.
