如何比较 sql 中 where 子句中的多个日期

Question

 select truckid 
 from truck_log 
 where '20160804' between ruck_log.pickupdate and truck_log.ETA  
   and '20160806' between truck_log.pickupdate and truck_log.ETA

当我执行此查询时，如何比较 where 子句中的两个日期，查询只接受第一个比较？

Answer 1

在 where 子句中添加“OR”而不是“AND”：

查询：

select truckid from truck_log 

where  ('20160804' between truck_log.pickupdate and truck_log.ETA) 

      or ('20160806' between truck_log.pickupdate and truck_log.ETA)

Answer 2

ruck_log 是错字吗，应该是 Truck_log？

如果为真，这

select truckid 
 from truck_log 
 where '20160804' between truck_log.pickupdate and truck_log.ETA  
   and '20160806' between truck_log.pickupdate and truck_log.ETA

将select所有要求日期介于取件日期和预计到达时间之间的行

          <-- 20160804   20160806 -->
pickupdate                           ETA

如果您只需要 select 一个或第二个，请使用 OR 子句而不是 AND。
