如何通過偏移量和per_page變量笨的方式連接查詢

Question

如何通過偏移和在下面的查詢perpage計數

 $this->db->select('*');  
     $this->db->from($this->table1); 
     $this->db->join($this->table2, 'plot.location_id = locations.location_id'); 
     $this->db->join($this->table3, 'plot.plot_type = plot_types.plot_id'); 
     $this->db->join($this->table4, 'plot.user_id = admin.id'); 


     $query = $this->db->get(); 
     return $query->result(); 

Answer 1

$this->db->limit(); 

可以限制你想通過返回的行數查詢

Answer 2

是的，我試圖用限制..它的工作原理感謝

下面是代碼

 $this->db->select('*');  
     $this->db->from($this->table1); 
     $this->db->join($this->table2, 'plot.location_id = locations.location_id'); 
     $this->db->join($this->table3, 'plot.plot_type = plot_types.plot_id'); 
     $this->db->join($this->table4, 'plot.user_id = admin.id'); 
     $this->db->order_by($this->table1.'.plot_id','DESC'); 
     $this->db->limit($per_page, $offset); 
     $query = $this->db->get(); 
     return $query->result();
