Eloquent从数据库中选择，获得比给定的unix时间戳更新的结果

I would like to select rows from my database newer than some specified UNIX timestamp specified in the parameters.

The column created_at is a datetime in the table tracks. The parameter $timestamp is a UNIX timestamp (an integer).

So I am trying with Tracks::where('created_at','>=',$timestamp)->get(); which simply returns all tracks, no matter which $timestamp I specify.

However I can see the type problem, and I have tried different things like writing 'UNIX_TIMESTAMP(created_at)' instead of created_at, but with no luck.

So I assume there is some elegant and simple way of doing this. Can you help me?

There are 2 ways to solve this.

1. Use Tracks::where(DB::raw('UNIX_TIMESTAMP(created_at)'),'>=',$timestamp)
2. Use a DateTime or Carbon object.

like this:

$timestamp = Carbon\Carbon::createFromTimestamp($timestamp);
Tracks::where('created_at','>=',$timestamp)->get();
