在mysql中選擇具體時間

Question

我們有一個名爲created的列，它是一個mysql時間戳。我必須選擇在前一天的下午5點到當天下午4:59之間創建的記錄。

假設我將日期範圍爲25-8-2014傳遞給該程序，它應該將所有創建的記錄在24-8- 2014 5:00 PM至25-8-2014 4:49 PM之間創建。我們如何編寫查詢來做到這一點？

Answer 1

您可以使用BETWEEN子句。 BETWEEN運算符選擇一個範圍內的值。這些值可以是數字，文本或日期。

語法：

SELECT column_name(s) 
FROM table_name 
WHERE column_name BETWEEN value1 AND value2; 

例子：

Select * from tableNawhere created between date1 and date2; 

注：在你的情況，date1應(date2 - 1day)

Answer 2

select * from your_table 
where created between 
curdate() - interval 1 day + interval 17 hour 
and 
curdate() + interval 16 hour + interval 59 minute; 

或

select * from your_table 
where created between 
date_format(now() - interval 1 day, '%Y-%m-%d 17:00:00') 
and 
date_format(now(), '%Y-%m-%d 16:59:00'); 

或

select * from your_table 
where created between 
concat(curdate() - interval 1 day, ' 17:00:00') /*note the whitespace before 17*/ 
and 
concat(curdate(), ' 16:59:59');
