CodeIgniter中select_avg（）的小数位数

Question

有没有办法在CodeIgniter中使用select_avg()只显示一个小数？

 $this->db  
      ->select_avg('Stars')
      ->from('Reviews') 
      $query=$this->db->get();  
      return $query->result(); 

Answer 1

试试这个

$this->db->select_avg(ROUND('Nr_stele'))->from('Recenzii as r');
$query = $this->db->get(); 
return $query->result_array();

  

检查codeigniter中的SQL ROUND() Function和$this->db->select_avg()
