php - 优化许多 "BETWEEN ? AND ?"where 子句

Question

我正在尝试抓取里程在一定范围内的车辆 $range和 $interval .目前，有大量between ? and ?极大地减慢查询速度的子句。有没有更好的方法来完成这个？我认为模运算可能有效，尽管 $range使它变得更加困难。

$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
