sql语句分别按日,按周,按月,按季统计金额

sql语句分别按日,按周,按月,按季统计金额

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 ]
