显示想要日期行的总记录

Question

我通过汇总结果从表中检索数据并显示在表格中。我想在date =＆＃39; 2014-01＆＃39;之间显示总和结果记录。和日期=＆＃39; 2014-04＆＃39;在2014-04栏目名称。然后，我想在2014-05检索到当前日期的其他总和结果。 我怎么能这样做？

SELECT MONTH(regist_timestamp) AS Month, YEAR(regist_timestamp) AS Year,
count(id) AS numberOfVisits FROM ash_members WHERE 
DATE(regist_timestamp) < CURDATE() GROUP BY 
DATE_FORMAT(`regist_timestamp`,'%Y/%m' )

Answer 1

在SELECT上设置日期格式，然后GROUP BY。试试 -

SELECT MONTH(regist_timestamp) AS Month, YEAR(regist_timestamp) AS Year, 
count(id) AS numberOfVisits, DATE_FORMAT(`regist_timestamp`,'%Y/%m' ) formatted_date
FROM ash_members
WHERE DATE(regist_timestamp) < CURDATE()
GROUP BY formatted_date
