mysql - 分别过去四个月的 Sum(count()) ？

Question

我必须分别找出过去 4 个月的总(计数)值和月份，我该如何做到这一点

表结构为

CREATE TABLE `lime_survey_16579` ( 
`id` int(11) NOT NULL auto_increment, 
`submitdate` datetime default NULL, 
`lastpage` int(11) default NULL, 
`startlanguage` varchar(20) collate utf8_unicode_ci NOT NULL, 
`token` varchar(36) collate utf8_unicode_ci default NULL, 
`16579X10X31` varchar(5) collate utf8_unicode_ci default NULLPRIMARY KEY (`id`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=480 ; 

此处 $survey = Lime_survey_16579 和 $temp= 16579X10X31 这里 16579X10X31 的值类似于 A1 A2 A3 ..

我如何才能给出类似的输出

tot month 

2 july 
4 aug 
6 sep 
9 oct 

有人可以帮我吗？

Answer 1

请尝试以下所有数据:

SELECT count(id) as tot, MONTHNAME(submitdate) as `month`
FROM lime_survey_16579
GROUP BY month(submitdate) 
ORDER BY month(submitdate)

要将数据限制为最近 4 个月，请尝试以下操作:

SELECT count(id) as tot, MONTHNAME(submitdate) as `month`
FROM lime_survey_16579
GROUP BY month(submitdate) 
ORDER BY month(submitdate) DESC
LIMIT 4
