Multiple SQL Joins from same table with Codeigniter

Question

I have a DB with 2 columns of ID that reference the same table

How do I do 2 joins to the same table, and be able to pull the data.

Here is what I have:

Answer 1

$this->db->select('*');
    $this->db->from('jobs');
    $this->db->join('company','company.cmp_name = jobs.cmp_name');
    $this->db->where('company.location', $data['location']);**strong text**

Answer 2

Just alias it differently:

$this->db->join('instructors as ialt', 'ialt.id = s._alt_instructor_id');
