Question

此查询之前有效，但也许我以某种方式更改了它..

select * from completed_games where date BETWEEN 2015-02-22 00:00:00 AND 2015-02-28 00:00:00

为什么这个查询不起作用，我该怎么写呢？

错误：

ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '00:00:00 AND 2015-02-28 00:00:00' at line 1

Answer 1

您的日期无效。您需要将它们括在引号之间。

select *
from completed_games
where date BETWEEN '2015-02-22 00:00:00' AND '2015-02-28 00:00:00'

Answer 2

您需要在日期字符串周围加上引号：

select * 
from completed_games 
where date BETWEEN '2015-02-22 00:00:00' 
    AND '2015-02-28 00:00:00'

Answer 3

如果您不需要检查时间，您甚至可以执行以下操作：

SELECT * 
FROM completed_games 
WHERE `date` BETWEEN '2015-02-22' AND '2015-02-28'

提示：尝试在关键字或特殊字符周围使用反引号（`）。

这种SQL语法在两个日期之间选择数据有什么问题？
