当列表的类型为date NOT timestamp时，MySQL检索过去24小时的数据

Question

I am trying to retrieve data for the passed 24 hours but I am getting nothing, but when I check on the table column (days) directly in db, I can find them. Here is my query:

select * from mytable
where
days between concat(date(date_sub(now(), interval 1 day))

Answer 1

between requires 2 arguments that specify the range:

select * from mytable
where days between date_sub(now(), interval 1 day) and now();

Or simply

select * from mytable
where days > date_sub(now(), interval 1 day);

Answer 2

您可以使用

select * from mytable where days > date_sub(CURDATE(),INTERVAL 1 DAY);
