从mysql中检索超过60天但小于90天的记录php

Question

我正在尝试在超过60天但超过90天的Mysql中查找记录。 超过60天的作品，但我似乎无法获得不超过89天的记录。

SELECT * FROM signings WHERE datediff(now(), signstart) > 60 < 90 

Answer 1

尝试

SELECT * FROM signings WHERE datediff(now(), signstart) > 60 and datediff(now(), signstart) < 90 

Answer 2

SELECT * FROM signings WHERE signstart BETWEEN 
     DATE_SUB(NOW(), INTERVAL 90 day) AND DATE_SUB(NOW(), INTERVAL 30 day)
