mysql 按时间段统计(年,季度,月,天,时)

按年汇总,统计:

select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y');

按月汇总,统计:

select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y-%m');

按季度汇总,统计:

select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by concat(date_format(col, '%Y'),FLOOR((date_format(col, '%m')+2)/3));

select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by concat(date_format(col, '%Y'),FLOOR((date_format(col, '%m')+2)/3));

按小时:

select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by date_format(col, '%Y-%m-%d %H ');

查询 本年度的数据:

SELECT * FROM mytable WHERE year(FROM_UNIXTIME(my_time)) = year(curdate())

查询数据附带季度数:

SELECT id, quarter(FROM_UNIXTIME(my_time)) FROM mytable;

查询 本季度的数据:

SELECT * FROM mytable WHERE quarter(FROM_UNIXTIME(my_time)) = quarter(curdate());

本月统计:

select * from mytable where month(my_time1) = month(curdate()) and year(my_time2) = year(curdate())

本周统计:

select * from mytable where month(my_time1) = month(curdate()) and week(my_time2) = week(curdate())

N天内记录:

WHERE TO_DAYS(NOW())-TO_DAYS(时间字段)<=N
