正如我可以从您的中猜到的，

timestamp

列的类型不是

date、datetime或timestamp

中的任何一个。它可能是

varchar

或

text

因此，当您尝试将

INTERVAL 1 DAY

添加到非时间类型的值时，会出现错误

您必须将

时间戳

列转换为任何

日期、日期时间或时间戳

数据类型

作为快速解决方案，您可以在查询中使用

STR\u TO\u DATE（）

函数：

CREATE VIEW `facebook_insights` AS
...
and STR_TO_DATE(t1.timestamp,'%m/%d/%Y') = STR_TO_DATE(t2.timestamp,'%m/%d/%Y') + INTERVAL 1 DAY

但是最好修改您的表以获得正确的数据类型。

正如我从您的中猜到的，

时间戳
