Oracle filter with LIKE method always zero result

Hi, Im working with CI and oracle right now but i have difficulties if i use LIKE method.

My code like this :

Code:

$this->db->select('COUNT(*) AS FOUND');
        $this->db->where($where);
        $row = $this->db->get('"ci_r_user_log"')->row();

 And the result is zero for FOUND

I try to look the query and the result like :

Code:

SELECT COUNT(*) AS FOUND FROM "ci_r_user_log" WHERE "ul_datetime_login" LIKE '23-09-2019%'

I try run the query with SQL Developer and get 4 data found. I checked and it's correct.

So why the query that run with CI is not working? But the query is good

Im sorry if my english is bad.
