mysql如何按月求和,时间格式为1430795781,第1张

SELECT FROM_UNIXTIME(`time`, '%c月份') AS mth,CONCAT(SUM(amount),'元')  as amount FROM tb GROUP BY mth

另外结果第一列不考虑年份吗?

易客CRM之前的版本中有一个报表是按月统计销售情况,最近有个客户想按周统计销售情况。按月统计的Sql语句比较好写,sql语句如下:

SELECT DATE_FORMAT(ec_salesorder.duedate,’%Y-%m’) as m, sum(ec_salesorder.total) as total, count(*) as so_count FROM ec_salesorder GROUP BY m ORDER BY m,也就是把duedate日期以月的形式显示,然后groupby,那么按周如何统计呢?

搜了一下mysql的manual,在这里找到一个解决方法,通过mysql的week函数来做,sql语句如下:SELECT WEEK(ec_salesorder.duedate) as m, sum(ec_salesorder.total) as total, count(*) as so_count FROM ec_salesorder GROUP BY m ORDER BY m,这个方法有个缺陷,不能显示年份,仅仅靠一个周数不方便查看统计信息。

继续研究mysql manual,在DATE_FORMAT函数介绍发现2个格式符和周有点关系:

%X Year for the week where Sunday is the first day of the week, numeric, four digitsused with %V

%x Year for the week, where Monday is the first day of the week, numeric, four digitsused with %v

把上面的Sql语句中改成:

SELECT DATE_FORMAT(ec_salesorder.duedate,’%x %v’) as m, sum(ec_salesorder.total) as total, count(*) as so_count FROM ec_salesorder GROUP BY m ORDER BY m

显示的结果如下:

m total so_count

2009 11 10000.00 3

2009 12 44000.00 5

如果周日为一周的第一天,那么sql语句应该为:

SELECT DATE_FORMAT(ec_salesorder.duedate,’%X %V’) as m, sum(ec_salesorder.total) as total, count(*) as so_count FROM ec_salesorder GROUP BY m ORDER BY m

结果应该没错,不出意外,易客CRM下个版本将增加按周统计销售情况的报表。
