测试表:

consume_record
字段1:consume (money类型)
字段2:date (datetime类型)

 

写sql语句分别按日,星期,月,季度,年统计销售额

--按日
select sum(consume),day([date]) from consume_record where year([date]) = '2006' group by day([date])

--按周quarter
select sum(consume),datename(week,[date]) from consume_record where year([date]) = '2006' group by datename(week,[date])

--按月
select sum(consume),month([date]) from consume_record where year([date]) = '2006' group by month([date])

--按季
select sum(consume),datename(quarter,[date]) from consume_record where year([date]) = '2006' group by datename(quarter,[date])
 

--按年

select sum(consume),year([date]) from consume_record where  group by year([date])
