Question

大家好我想在星期一上午10点到星期二上午7点之间编写一个排除任何CHECKIN_DATE（TIMESTAMP）的查询。我发现了两个有趣的函数DAYOFWEEK和HOUR，遗憾的是我不知道如何编写它，这是我目前处理查询的地方

SELECT * FROM LIST_CHECKIN_AUDIT 
WHERE DOCUMENT_TYPE = 'DABL'
AND CHECKIN_DATE BETWEEN (DAYOFWEEK(CHECKIN_DATE) = '2' AND HOUR(CHECKIN_DATE) = '9') AND (DAYOFWEEK(CHECKIN_DATE = '2' AND HOUR(CHECKIN_DATE = '7')

提前致谢！

如果您尝试排除 CHECKIN_DATE在星期一上午10点到星期二上午7点之间的任何记录，那么我认为以下内容适合您。

SELECT *
  FROM LIST_CHECKIN_AUDIT 
 WHERE DOCUMENT_TYPE = 'DABL'
   AND (DAYOFWEEK(CHECKIN_DATE) <= 2 AND HOUR(CHECKIN_DATE) <= '9'))
    OR (DAYOFWEEK(CHECKIN_DATE) >= 3 AND HOUR(CHECKIN_DATE) >= '7'))

在db2上设置时间戳周围的参数
