You could also do something like this, if you want to find duplicate values in the column 'name':

Example:

$duplicateRecords = DB::select('name')
              ->selectRaw('count(`name`) as `occurences`')
              ->from('users')
              ->groupBy('name')
              ->having('occurences', '>', 1)
              ->get();

Then you need to loop through your collection and delete the items.

foreach($duplicateRecords as $record) {
    $record->delete();
}

How to Remove Duplicate Rows in Laravel, I have more than row with the same data but different in id (because it's unique) Remove duplicated rows how get only first row from duplicated ??? thanks https://laravel.com/docs/5.5/eloquent#retrieving-single-models. FYI this will delete ALL the rows, so if you have a row 2 times, then it will delete BOTH rows, ending up with NO rows. Make sure this is exactly what you want! – Sliq May 27 '19 at 14:31


With Eloquent:

App\Model::where('mobile_number', '0123456789')->delete();

With the Query Builder:

DB::table('some_table')->where('mobile_number', '0123456789')->delete();
EDIT

The above will delete all rows with mobile_number 0123456789. If you want to keep one, use this:

// Get the row you don't want to delete.
$dontDeleteThisRow = App\Model::where('mobile_number', '0123456789')->first();

// Delete all rows except the one we fetched above.
App\Model::where('mobile_number', '0123456789')->where('id', '!=', $dontDeleteThisRow->id)->delete();

    $same_data_before = clone $same_data;

    $same_data_before->where('id', '!=', $top->id)->delete();
