Convert a raw SQL containing a subquery in the SELECT clause into a CodeIgniter query builder script

How can I convert this SQL query into CodeIgniter's query builder?

SELECT
    t.idkas,
    t.tglkas,
    (
        SELECT (SUM(kredit))-(SUM(debet))  
        FROM kaskecil t2 
        WHERE t2.idkas <= t.idkas
    ) AS total
FROM kaskecil t
Solution 
  • $this->db->select("t.idkas, t.tglkas, ((SELECT SUM(kredit) - SUM(debet) FROM kaskecil t2 WHERE t2.idkas <= t.idkas) AS total)", FALSE);
$this->db->from("kaskecil t");
$query = $this->db->get();
