在 laravel-8 中获取最后一个 id 表单数据库

Question

I want to get only the last inserted data from my database. Here, I get all data from the database but I want only the last value. This is ProductController.php

function indextwo() 
{
    return DB::select("select * from  products");
}

This is web.php

Route::get('products_link', [ProductController::class, 'indextwo']);

Here is my current output:

Answer 1

You can get the last id using Query Builder and Eloquent .

Query Builder

function indextwo() {
    return DB::table('products')->orderBy('id', 'DESC')->first();
}

Eloquent

function indextwo() {
    return Product::orderBy('id', 'DESC')->first();
}

Answer 2

Maybe you can use latest() function for get

$user = DB::select("select * from  products")
            ->latest()
            ->first();

Answer 3

Maybe you can use Model name direct in controller like your model name is "Product" and also use limit() and latest()

$user = Products::latest()->limit(1);

Answer 4

A very simple way you can follow

Product::query()->latest()->first() 

It will return you the latest inserted data according to order by id desc.

Another way:

Product::query()->orderByDesc('id')->first();
