I need to get the meta key meta value from the database

I have to take the Metakey full_dolar that does not match metakey post_id of the table Postmeta and based on the Post_status publish and draft, accepted. That does not match table ID posts.

$title = $_POST['post_title'];
        			$post_id = $_POST['post_id'];

        			$sim_dolar = "SELECT meta_value FROM $wpdb->postmeta WHERE meta_key = 'full_dolar' = '{$title}' AND meta_key =  post_id != {$post_id } AND $wpdb->posts post_status = 'publish,draft' AND ID != {$post_id} " ;
