php - 在 Codeigniter 中比较一个值与两列

Question

我的平均值假设为 38% 然后我在 Codeigniter 中有像这样的值

mark_from   mark_to         Remarks
0                9          Failed
10               19         Also failed
89               99         Excellent

I Have used this Query

$remarks = $this->db->select('remark')->where('mark_from >=',$average)->where('mark_to <=',$average)->get('remarks')->result_array();

Answer 1

跳出框框思考:

$this->db->select('remark')
         ->where((int) $average.' BETWEEN mark_from AND mark_to')
         ->get('remarks');
