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]
按周统计

///查询本周

SELECT tm,YEARWEEK( tm ) ，YEARWEEK( NOW( ) ) 

FROM  `ims_lingmei_car_cardlog` 

WHERE YEARWEEK(tm) = YEARWEEK( NOW( ) ) 
LIMIT 0 , 30
