我正在尝试从表中获取记录总数并使用以下 MySQL 查询:

SELECT COUNT(*) AS cnt FROM `info` WHERE 1 GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') ORDER BY signup_date DESC

但它导致以下错误:

SQL 错误(1055):ORDER BY 子句的表达式 #1 不在 GROUP BY 子句中,并且包含在功能上不依赖于 GROUP BY 子句中的列的非聚合列“rentown.info.signup_date”;这与 sql_mode=only_full_group_by 不兼容。[SELECT COUNT( ) AS cnt FROM infoWHERE 1 GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') ORDER BY signup_date DESC]

这是我的表格格式:

+ Options
    id  email   signup_date     ip  city_name   firstname   address     state   lastname    city    zipcode     phonenumber     current_url     creditscore

错误消息是不言自明的。您只能按出现在GROUP BY子句或聚合中的列进行排序。为了快速修复,只需按照分组时使用的相同术语进行排序。

SELECT COUNT(*) AS cnt
FROM `info`
GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d')
ORDER BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') DESC

对于记录总数,这应该足够了:

SELECT COUNT (*) AS cnt
FROM 'info'
ORDER BY signup_date DESC
