在 db2 上围绕时间戳设置参数

Question

大家好，我想编写一个查询，排除周一上午 10 点到周二上午 7 点之间的任何 CHECKIN_DATE (TIMESTAMP)。我发现了两个有趣的函数DAYOFWEEK 和HOUR不幸的是我不知道怎么写，这是我目前查询的地方

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 介于周一上午 10 点和周二上午 7 点之间的任何记录，那么我认为以下内容应该适合您。

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'))
