eloquent fetch records within recent 3 hours - php

Question

I need to fetch all the records which is inserted between past 3 hours to current(now). I am using laravel framework(eloquent orm).
I tried this found here
$lb = \DB::table('myTable')->whereRaw('created_at = DATE_ADD(NOW(), INTERVAL -3 HOUR');
But it return NULL. Is there any way I can do using eloquent but not Raw Query?
Any Help would be appreciated.

Answer 1

Laravel comes with Carbon, a nice library to handle dates, which can be used in combination with Eqlouent.
Example:
\DB::table('myTable')
->where('created_at', '>',
Carbon::now()->subHours(3)->toDateTimeString()
);

Answer 2

We can use PHP DateTime. Like this,
$date = new \DateTime();
$date->modify('-3 hours');
$formatted_date = $date->format('Y-m-d H:i:s');
$lb = \DB::table('myTable')->where('created_at', '>',$formatted_date);
In above code what we're doing is creating date string with PHP and using that in query.

Answer 3

add this scope to your model:
public function scopeRecent($query)
{
return $query-> whereDate('created_at ' , '=',Carbon::today())
->whereTime('created_at' , '>',Carbon::now()->subHours(3));
}
then use the scope in controller :
$posts= Post::recent()->pluck("id")->toArray();

Answer 4

Try This
$lb = \DB::table('myTable')->whereRaw('created_at >= DATE_SUB(NOW(), INTERVAL 3 HOUR)')
In your statement you are using = (206-07-27 11:30:00) instead >= (206-07-27 11:30:00)

Answer 5

try this,
include use Illuminate\Support\Facades\DB; namespace in your controller
and try this code
$results = DB::table('yourtable')->select('*')->where('created_at >= DATE_SUB(NOW(),INTERVAL 1 HOUR)')->get();

Answer 6

as created_at is datetime field, you can use this
\DB::table('myTable')->where('created_at', '<', Carbon::now()->subHours(3)->toDateTimeString())->get();
