删除一个数据后，如何以升序从数据库中检索新数据？

Question

I have contact names which are arranged in ascending order with their name.

But when I delete one contact name , I want to retrieve the next to the deleted one in ascending order.

But I cannot make it right. Right now I'm retrieving with id but its not effective.

    function deleteContact($id)
    {
            $data = Contact::where('id', '>', $id)->first();

            $contact = Contact::find($id);
            $contact->delete();

            return $data;

        }

Answer 1

if you want to show order By id

function deleteContact($id)
{
  $contact = Contact::find($id);
  $contact->delete();

  $data = Contact::orderBy('id','asc')->get();
  return $data;
}

if you want to show order by created date from last to first

function deleteContact($id)
{
  $contact = Contact::find($id);
  $contact->delete();

  $data = Contact::orderBy('created_at','DESC')->get();
  return $data;
}

Answer 2

Try to use Order By

Eloquent

$data = Contact::orderBy('name', 'ASC')->get();

query builder

$data = DB::table('contact')->orderBy('name','ASC')->get();

Answer 3

Try this.

function deleteContact($id)
{


        $contact = Contact::find($id);
        $contact->delete();

        $data = Contact::orderBy('name','asc')->first();
        return $data;

    }

Answer 4

Just use orderBy while querying Contacts not by $data = Contact::where('id', '>', $id)->first(); ,

function deleteContact($id)
{
    $contact = Contact::find($id);
    $contact->delete();

    $data = Contact::orderBy('name','asc')->first();
    return $data;
}

The orderBy method allows you to sort the result of the query by a given column(here you have to give 'name' column.)

For more details check this Ordering, Grouping, Limit, & Offset

Try this and comment if you have any query.

Answer 5

try this. First delete then retrieve data in ascending order.

function deleteContact($id){  
    Contact::where('id', '=', $id)->delete();
    $data = Contact::select('*')->orderBy('id', 'asc')->get();
    return $data; }
