select raw laravel code example

Example 1: laravel join

Inner Join 	: ->join('contacts', 'users.id', '=', 'contacts.user_id')
Left Join 	: ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
Right Join 	: ->rightJoin('posts', 'users.id', '=', 'posts.user_id')
Cross Join 	: ->crossJoin('colors')

Advance Queries : 
----------------- 
 		->join('contacts', function ($join) {
            $join->on('users.id', '=', 'contacts.user_id')
                 ->where('contacts.user_id', '>', 5);
        })

Example 2: laravel not in query

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

$results = DB::select( DB::raw("SELECT * FROM some_table WHERE some_col = :somevariable"), array(
   'somevariable' => $someVariable,
 ));

DB::statement( 'ALTER TABLE HS_Request AUTO_INCREMENT=:incrementStart', array('incrementStart' => 9999) );
