sql 日周月统计和

sql 本日\本周\本月统计 SQL的本月统计和本周统计 本月统计(MySQL) select * from booking where month(booking_time) = month(curdate()) and year(booking_time) = year(curdate()) 本周统计(MySQL) select * from spf_booking where month(booking_time) = month(curdate()) and week(booking_time) = week(curdate())   [SQLServer] 表名为：tableName 时间字段名为：theDate 查询本月的记录 select * from tableName where DATEPART(mm, theDate) = DATEPART(mm, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE()) 查询本周的记录 select * from tableName where DATEPART(wk, theDate) = DATEPART(wk, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE()) 查询本季的记录 select * from tableName where DATEPART(qq, theDate) = DATEPART(qq, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE()) 其中:GETDATE()是获得系统时间的函数。   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]    统计博客聚合用户点击次数 SELECT author, SUM(hits) AS hits FROM infos GROUP BY author ORDER BY hits DESC 统计昨天的记录 SELECT * FROM infos WHERE (DATEDIFF(d, pubdate, GETDATE()) = 1) 统计本周的记录 SELECT * FROM infos WHERE (DATEPART(yy, pubdate) = DATEPART(yy, GETDATE())) AND (DATEPART(week,       pubdate - 1) = DATEPART(week, GETDATE())) 统计本月的记录: SELECT * FROM infos WHERE (DATEPART(yy, pubdate) = DATEPART(yy, GETDATE())) AND (DATEPART([month],       pubdate - 1) = DATEPART([month], GETDATE()))
