php - 按 CURDATE() 过滤查询

Question

SELECT *
FROM `summary`
WHERE submit_date = curdate()
AND submit_date > '06:00'
AND submit_date < '21:00'
LIMIT 0 , 30

这是取消包括今天在内的所有日期？submit_date 是一个显示有 DATETIME 的列，它没有像应有的那样过滤掉它们。我错过了什么？谢谢！

Answer 1

您的 2 个限制条件应与列返回的值进行比较TIME()，DATETIME第一个条件应仅限于该DATE()部分。

SELECT *
FROM `summary`
WHERE
  /* Truncate to the date only to compare against CURDATE() */
  DATE(submit_date) = curdate()
  /* And truncate to the TIME() to compare against these time literals. */
  /* note also that the time literals may need seconds as well */
  AND TIME(submit_date) > '06:00:00'
  AND TIME(submit_date) < '21:00:00'
LIMIT 0 , 30

Answer 2

您应该只比较 submit_date 的日期部分与当前日期的日期部分，然后是小时部分，如下所示：

SELECT *
FROM `summary`
WHERE 
    DATE(submit_date) = curdate()
AND HOUR(submit_date( BETWEEN 6 AND 21
LIMIT 0 , 30
