MySQL按年度、季度、月度、周、日、小时 编写SQL统计数据案例

SELECT *FROM person_base_info;

小时维度查询

1、查询当前时间的前2小时之前的数据

select * from person_base_info WHERE create_time < DATE_SUB(NOW(), INTERVAL 2 HOUR)

2、查询当前时间7天之前的数据、7天之前之内的数据，刚好7天的数据

SELECT count(uuid) AS cont FROM person_base_info WHERE DATE(create_time) < DATE_SUB(CURDATE(), INTERVAL 7 DAY);
SELECT count(uuid) AS cont FROM person_base_info WHERE DATE(create_time) > DATE_SUB(CURDATE(), INTERVAL 7 DAY);
SELECT count(uuid) AS cont FROM person_base_info WHERE DATE(create_time) = DATE_SUB(CURDATE(), INTERVAL 7 DAY);

按天统计

-- 第一种方式

SELECT DATE(create_time) createTime,count(uuid) countNum FROM person_base_info 
GROUP BY DATE(create_time) ORDER BY DATE(create_time) DESC;

-- 第二种方式
SELECT DATE_FORMAT(create_time,'%Y-%m-%d')createTime ,COUNT(uuid) countNum FROM person_base_info 
GROUP BY DATE_FORMAT(create_time,'%Y-%m-%d')

按月统计

SELECT DATE_FORMAT(create_time,'%Y-%m')createTime ,COUNT(uuid)countNum
FROM person_base_info 
GROUP BY DATE_FORMAT(create_time,'%Y-%m')

-- 另一种方式
SELECT MONTH(create_time) createTime,count(uuid) countNum FROM person_base_info 
GROUP BY MONTH(create_time) ORDER BY MONTH(create_time) DESC;

按周统计

按当年当月统计

select month(create_time) months,COUNT(uuid)AS countNum from person_base_info where month(create_time) =
month(curdate()) and year(create_time) = year(curdate())

按季度统计

--  第一季度:1月-3月 第二季度:4月-6月 第三季度:7月-9月 第四季度:10月-12月
SELECT QUARTER(create_time) AS 季度,count(uuid) AS countNum   
FROM person_base_info
GROUP BY QUARTER(create_time)
ORDER BY QUARTER(create_time) DESC;

 按年统计

SELECT DATE_FORMAT(create_time,'%Y')createTime ,COUNT(uuid)countNum
FROM person_base_info 
GROUP BY DATE_FORMAT(create_time,'%Y')

--第二种方式
SELECT YEAR(create_time) createTime,count(uuid) countNum FROM person_base_info
GROUP BY YEAR(create_time)
ORDER BY YEAR(create_time) ASC;
