优化许多＆＃34; BETWEEN？和？＆＃34;哪个条款

Question

我试图抓住里程数在$range和$interval之内的车辆。目前，有大量between ? and ?条款正在大大减慢查询速度。有没有更好的方法来实现这一目标？我认为模运算可能会起作用，尽管$range会使其变得更加困难。

$interval = 15000;
$range = 5000;
$max = 3000000;

for ($i = $interval; $i < $max; $i += $interval)
{
    $between = [
        $i - $range,
        $i + $range,
    ];

    // generates "WHERE mileage BETWEEN ? AND ? OR mileage BETWEEN ? AND ? ..."
    $query->orWhereBetween('mileage', $between);
}

Answer 1

select .. where (mileage>=15000) and ((mileage-10000) mod 15000)<=10000
