如何比较php codeigniter中的日期和年份

Question

My model

public function get_payscale() {
    $this->db->from('payscale P')->join('employee E','E.employee_id = P.employee_id ');
    $this->db->where('P.payscale_date',date('Y-m'));
    return $this->db->get()->result_array();
}   

I want to compare only month and year with the db which in the format y-m-d, where i want only to retrieve the y-m using where clause. any help would be appreciated

Answer 1

Use like this :

$this->db->where('EXTRACT(YEAR_MONTH FROM P.payscale_date)',date('Ym'));

This query will extract the Year and month from the date given column like 201605 (2016-05-21)
