SQL按照日、周、月、年统计数据(转)

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])



--指定日期 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]
