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 ');
