如:
表:consume_record
字段:consume (money类型)
date (datetime类型)
请问怎么写四条sql语句分别按日,按周,按月,按季统计消费总量.
如:1月 1200元
2月 3400元
3月 2800元
--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 group by year([date])
--指定日期你就看上面的例子变通下呀,无非就是一个聚合函数和Group by
select [date],sum(consume) from consume_record where [date] between ‘2006-06-01‘ and ‘2006-07-10‘ group by [date]
