mysql 統計七天數據並分組

業務背景

統計各機型最近7天bug數量來支撐一張圖表：

sql需要查詢最近七天數據並按每天和機型進行分組

思路

1. 查詢最近7天的數據

select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(column_time);

拓展

查詢最近一天的數據

select * from table where to_days(column_time) = to_days(now());
select * from table where date(column_time) = curdate(); 

查詢最近一個月的數據

select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) <= date(column_time);

2. 查詢需要的列並分組

例如：

SELECT
	DATE_FORMAT( create_time, '%Y-%m-%d' ) days,
	phone_model ,
	count(*) count 
FROM
( SELECT * FROM trial_feedback_pdm WHERE DATE_SUB( CURDATE( ), INTERVAL 7 DAY ) <= date( create_time) ) as day
GROUP BY
	 days,phone_model;
