WhereRaw() is a function of Laravel query builder which puts your input as it is in the SQL query's where clause. ,Think of it as the where() function whose input argument will not be processed before inserting into queries. ,Now Laravel put this where clause as it is in your query, like below: ,WhereRaw: Sometimes you may need to use a raw expression in a query. These expressions will be injected into the query as strings.

See the example below:

$Query = DB::table('some_table') - > where('YEAR(date)', 'YEAR(CURRENT_DATE)');

In this Laravel will resolve your arguments to build a query. Which will result in the following query because your input will be treated as some field and its its value :

SELECT * FROM `some_table`

And now if you use whereRaw like:

$Query = DB::table('some_table') - > whereRaw('YEAR(date) = YEAR(CURRENT_DATE)');

Now Laravel put this where clause as it is in your query, like below:

SELECT * FROM `some_table`

Sometimes you may need to insert an arbitrary string into a query. To create a raw string expression, you may use the raw method provided by the DB facade:, Database ,Running Database Queries Chunking Results Streaming Results Lazily Aggregates ,You may use whereJsonLength method to query JSON arrays by their length:

You may use the table method provided by the DB facade to begin a query. The table method returns a fluent query builder instance for the given table, allowing you to chain more constraints onto the query and then finally retrieve the results of the query using the get method:

< ? php

namespace App\ Http\ Controllers;

use App\ Http\ Controllers\ Controller;
use Illuminate\ Support\ Facades\ DB;

class UserController extends Controller {
    * Show a list of all of the application's users.
    * @return \Illuminate\Http\Response
   function index() {
      $users = DB::table('users') - > get();

      return view('user.index', ['users' => $users]);

Laravel has a great database mechanism called Eloquent, also a powerful Query Builder, but sometimes it makes sense to just use plain SQL, in the form of Raw Queries. In this article, I will show you the most common examples of this approach.,A pretty typical example is when you have an SQL statement from some older project, and you need to convert it to Eloquent or Query Builder.,In my experience, it’s often used in database migrations, when some table structure changes and old data needs to be updated with a new structure. ,If you need to execute some SQL query, without processing any results, like INSERT or UPDATE without any parameters, you can use DB::statement().

Example from Laravel documentation:

$users = DB::table('users') -
   > selectRaw('count(*) as user_count, status') -
   > where('status', '<>', 1) -
   > groupBy('status') -
   > get();

To demonstrate SQL injection in the whereRaw RawMethod, let’s take a look at the following code: ,Before we dive into examples of Laravel SQL injection, let’s take a look at what SQL injection is. ,This will cause the application to return zero rows or crash. This behavior shows the existence of SQL injection vulnerability in the whereRaw part of our initial query. ,The value for id is defined by user input. Let’s look at what happens when a user enters the following value: 

SELECT * FROM users WHERE username = 'john.doe'
