[eluser]Mitja B.[/eluser]
Hello, i am searching in user guide and google but i can not find how can i use mysql_fetch_assoc in CI

This is my code

Code:

$query = $this->db->query("SELECT pool_id
                  FROM pool_question
                  WHERE active = 1
                  ORDER BY question_id DESC
                  LIMIT 1");
