Question

我在旅行CRS protal工作。对于酒店预订我想阻止酒店取决于截止日期。

 SELECT * FROM (`crs_service_supplier_details` as crs) JOIN `crs_service_room_type_detail` as Room ON `crs`.`service_apartment_id`=`Room`.`service_id` JOIN `crs_room_type` as crt ON `Room`.`room_type_id`=`crt`.`room_type_id` JOIN `crs_service_off_dates` as ccod ON `crs`.`service_apartment_id`=`ccod`.`co_service` WHERE `crs`.`city` like '%Chennai%' AND ('2016-10-27' NOT between ccod.cut_off_from AND ccod.cut_off_from) AND ('2016-10-28' NOT between ccod.cut_off_to AND ccod.cut_off_to) AND `Room`.`edate` > '2016-10-27' GROUP BY `crs`.`service_apartment_id`

这是查询，但问题是切入了两天

co_id   co_service  cut_off_from    cut_off_to  cut_off_release_days cut_off
1       1       2016-10-20      2016-10-22          0               2016-10-20
2       1       2016-10-27      2016-10-28          0               2016-10-28

如果我在2016-10-20和2016-10-22之间进行搜索，则会获得＆＃34; 2016-10-27 and 2016-10-28＆＃34;并显示结果。

如果我在2016-10-27和2016-10-28之间进行搜索，则会获得＆＃34; 2016-10-20 and 2016-10-22＆＃34;并显示结果。它不会阻止任何系统的位置。请给出一些解决这个问题的想法？

可能是你的查询不对。可能这会有所帮助，只需更改BETWEEN逻辑：

AND ('2016-10-27' NOT BETWEEN ccod.cut_off_from AND ccod.cut_off_to)
AND ('2016-10-28' NOT BETWEEN ccod.cut_off_to AND ccod.cut_off_from)

使用上述内容。

BETWEEN的原始代码没有意义：

AND ('2016-10-27' NOT BETWEEN ccod.cut_off_from AND ccod.cut_off_from)
AND ('2016-10-28' NOT BETWEEN ccod.cut_off_to AND ccod.cut_off_to)

因为它是在同一列之间进行的。

如何从db获取记录？
