Question

当天是4，月份是10。如何查询月份在start_month和end_month范围之间的价格，它们的日期也在一个范围之间？

start_day，start_month，end_day和end_month可以在数据库中变量。

我当前的查询：

$price = FrontendModel::getDB()->getVar('SELECT p.price FROM appartments_pricing as p WHERE (p.days_start >= ? AND p.months_start >= ?) AND (p.days_end <= ? AND p.months_end <= ?) AND p.appartment_id = ?', array($day,$month, $day, $month, $appartment_id));

好的另一个选择：

mysql> select
           ap_id, price,
           date(concat('2000', '-', months_start, '-', days_start)) as start,
           date(concat('2000', '-', months_end, '-', days_end)) as end
           from x
           having date('2000-10-4') > start and date('2000-10-4') < end;

+-------+-------+------------+------------+
| ap_id | price | start      | end        |
+-------+-------+------------+------------+
|    32 |    15 | 2000-01-01 | 2000-12-31 |
+-------+-------+------------+------------+

如果您希望白天在范围days_start <= day <= days_end内，那么您需要切换查询（月份相同）：

$price = FrontendModel::getDB()->getVar('SELECT p.price FROM appartments_pricing as p WHERE (p.days_start <= ? AND p.months_start <= ?) AND (p.days_end >= ? AND p.months_end >= ?) AND p.appartment_id = ?', array($day,$month, $day, $month, $appartment_id));

如何查询开始日/月和结束日/月之间的价格
