How to run left outer join SQL query in laravel

Question

I am unable to write this query in laravel using query builder:

```
SELECT pt.name, IF(up.permission_id IS NULL,'false','true') permission
    FROM mercuri_permission_type pt 
    LEFT OUTER JOIN mercuri_user_permission up 
    ON pt.id = up.permission_id AND up.user_id = $user_id
```

Answer 1

You should do multi left join to handle this; But I suggest you use doctrine ORM and run this query on doctrine. In order to use Doctrine in Laravel the links below would be useful:
