sql語句分別按日,按周,按月,按季統計金額

如:?
表:consume_record?
字段:consume?(money類型)?
date?(datetime類型)?

請問怎么寫四條sql語句分別按日,按周,按月,按季統計消費總量.?
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])?

?

--指定日期你就看上面的例子變通下呀，無非就是一個聚合函數和Group?by?

select?[date],sum(consume)?from?consume_record?where?[date]?between?'2006-06-01'?and?'2006-07-10'?group?by?[date]?
