如何使用 between 将简单的 SQL 查询转换为 CodeIgniter？

Question

请帮助我，我想将一个简单的 SQL 语句转换为 Codeigniterdate($fromDate) BETWEEN vehicle_register.start_dt AND vehicle_register.end_dt

Answer 1

试试这个Method chaining，

$this->db->select('*');

$this->db->from('yourTableName');

$this->db->where('date('.$fromDate.') >=', 'vehicle_register.start_dt');

// >= will get conditional date too so please keep it as your reqirement

$this->db->where('date('.$fromDate.') <=', 'vehicle_register.end_dt');

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

if($query->num_rows() > 0){

  //return $query->result();//according to your need

}else{

  //return array();//according to your need

}
