mysql - 如何在 MySQL 中检查日期时间是否等于明天

Question

如果数据 created_at Datetime 列等于明天日期，我想检索 mysql 表数据，例如:

SELECT * FROM sales_order where created_at = tomorrow_date; 

Answer 1

您可以使用以下解决方案，使用 DATEDIFF和 DATE_ADD :

SELECT * 
FROM sales_order 
WHERE DATEDIFF(created_at, DATE_ADD(CURDATE(), INTERVAL 1 DAY)) = 0;

或仅使用 DATEDIFF 的更简单的解决方案:

SELECT * 
FROM sales_order 
WHERE DATEDIFF(created_at, CURDATE()) = 1

DATEDIFF() returns expr1 − expr2 expressed as a value in days from one date to the other. expr1 and expr2 are date or date-and-time expressions. Only the date parts of the values are used in the calculation. - from MySQL docs.
