mysql - Return random row in Laravel 4 -

i have testimonial table display on main page on laravel 4 project. usual run query random row:

select * `testimonials` `id`=".mt_rand(1,3); 

but error when trying run it:

sqlstate[42000]: syntax error or access violation: 1064 have error in sql syntax; check manual corresponds mysql server version right syntax use near '".mt_rand(1,3)' @ line 1 (sql: select * `testimonials` `id`=".mt_rand(1,3);) (bindings: array ( 0 => 1, ))  

here controller:

        public function showhome() {             db::select('select * `testimonials` `id`=".mt_rand(1,3);', array(1));     return view::make('home.index', array('pagetitle' => 'home')); } 

another side question how display information in home.blade.php template?

i usual while loop , $row['assoc_array']

$testimonial = db::table('testimonials')->where('id', mt_rand(1, 3))->first(); return view::make('home.index', array('pagetitle' => 'home', 'testimonial' => $testimonial)); 

this should provide variable called "testimonial" can use in view.
