I have here my sample query using codeigniter. I'm using this to get data satisfying my where condition.

MODEL:

    function quarterly1_sales($year_date, $q1_start){
     $where = array(
     'status'   => 'purchased',
     'payment.paymentdate >=' => $q1_start,
     'payment.paymentdate <=' => 'DATE_ADD('.$q1_start.',INTERVAL 1 QUARTER)');
    return $this->db
    ->select('COUNT(payment.keyid) AS rec_count')
    ->select('product_key.client_name, product_key.contact_email, product_key.status, product_key.id, payment.paymentdate, (payment.id) as pid,payment.subscription_type')
    ->from('product_key')
    ->where($where)
    ->join('payment', 'payment.keyid=product_key.id', 'left outer')
    ->group_by('product_key.id')
    ->get()
    ->result(); 
    }

CONTROLLER:

if($data['filter'] == 'quarterly'){
//1st quarter of the year
    @$q1_start = date('Y-m-d', strtotime(date($year_date).'-01-01'));
$data['quarterly1_sales'] = $this->basemodel->quarterly1_sales($year_date, $q1_start);
$this->load->view('sales', $data);          
}

VIEW:

if($filter == 'quarterly'){
    $title = "Quarterly Sales Summary for ".$date_year;

    echo "<br /><strong>".$title."</strong></div>
        </tr>"<tr>
    <th>Name</th>
    <th>Email Address</th>
    <th>Payment Date</th>
    <th>Subtotal Amount</th>

";

    foreach ($quarterly1_sales as $quarter1) :

        echo $client_name = $quarter1->client_name;
        echo $paymentdate = $quarter1->paymentdate;
        echo $email = $quarter1->contact_email;
        echo $recount= $quarter1->rec_count;
        echo $sum_amount = $recount * 588;
    if($recount == 0){
        $display = "display:none;";
    }else{
        $display = "";
    }

endforeach;

My problem is, there shouldn't be any result since my data starts with 2012 and 2013 yet it outputs everything. Hope someone could help me on this. Thank you.

Codeigniter 的活动记录类会自动转义传递给where()函数的所有内容。因此，您对 MySQL 函数的调用将DATE_ADD()作为字符串传入并由 MySQL 逐字处理，而不是被评估。要解决此问题，请将 where 子句移至单独的函数调用并将第三个参数设置为 FALSE，关闭转义。

$where = array(
     'status'   => 'purchased',
     'payment.paymentdate >=' => $q1_start);
    return $this->db
    ->select('COUNT(payment.keyid) AS rec_count')
    ->select('product_key.client_name, product_key.contact_email, product_key.status, product_key.id, payment.paymentdate, (payment.id) as pid,payment.subscription_type')
    ->from('product_key')
    ->where($where)
    ->where('payment.paymentdate <=', 'DATE_ADD('.$this->db->escape($q1_start).',INTERVAL 1 QUARTER)', FALSE)
    ->join('payment', 'payment.keyid=product_key.id', 'left outer')
    ->group_by('product_key.id')
    ->get()
    ->result();
