Count row divided by count row - php

Question

I have some problem with MySQL syntax in CI this is my table
id_data | nama_depan | nama_belakang | gender | luas_lantai | jenis_lantai
| status
I already tried code bellow and show error
Message: Object of class CI_DB_mysqli_result could not be converted to
int
public function getStatus1($status){
$str = "SELECT count(status)
FROM data_latih WHERE status = 1 ";
$str1 = "SELECT count(status)
FROM data_latih ";
$query = $this->db->query($str);
$query1 = $this->db->query($str1);
return $query / $query1;
}
expected output is decimal number of count status = 1 divided by count all rows
EDIT : Found the answer, thank you so much guys i'm new in programming so bear with me :)))

Answer 1

The problem is that you are trying to divide an Object by the Object which does not make any sense, Try this CI way,
public function getStatus1($status){
$this->db->count_all_results('data_latih ');
$this->db->where('status ', '1');
$this->db->from('data_latih ');
$result1 = (float)$this->db->count_all_results();
$result2 = (float)$this->db->count_all('data_latih');
return $result1 / $result2 ;
}

Answer 2

You can actually handle this with a single query:
SELECT
SUM(status = 1) / COUNT(status) AS result
FROM data_latih;
Regarding your PHP code, I would recommend assigning aliases to the various counts, and then accessing those aliases.
$sql = "SELECT SUM(status = 1) / COUNT(status) AS result FROM data_latih";
$result = $this->db->query($sql);
if ($row = $result->fetch_array()) {
echo $row['result'];
}
