SQL语句例一：求某一字段在某一时间段内数量的总和

　　表名 销售 字段有：编号 金额 统计这个表在某一时间段内金额的总和

　　select sum(金额) from 表 where 条件

　　SQL语句例二：SQL读出记录并统计出某一字段的总和

　　select * ,SUM(字段) from 表名 where 条件 group by 字段

　　SQL语句例三：SQL语句按每天、每月、每年统计出销售总额

　　表名： 订单 字段有Ordertime(订单时间),money(金额)

　　根据订单时间统计每天、每月、每年的销售总额

　　1、每年

　　select year(ordertime) 年，

　　sum(money) 销售合计

　　from 订单

　　group by year(ordertime)

　　2、每月

　　select year(ordertime) 年，

　　month(ordertime) 月,

　　sum(money) 销售合计

　　from 订单

　　group by year(ordertime)，

　　month(ordertime)

　　3、每日

　　select year(ordertime) 年，

　　month(ordertime) 月,

　　day(ordertime) 日，

　　sum(Total) 销售合计

　　from 订单

　　group by year(ordertime)，

　　month(ordertime),

　　day(ordertime)

　　SQL语句例四：统计某月销售量前10

　　表名: 销售

　　字段: 编号, 商品名称 价格 日期

　　统计某月商品销量最大的商品前10个商品及销量。

　　SELECT DISTINCT TOP 10 商品名称, SUM(价格) AS 产品总价, COUNT(*) AS 销量 FROM 销售 GROUP BY title

　　加上月份：

　　SELECT DISTINCT TOP 10 商品名称, SUM(价格) AS 产品总价, COUNT(*) AS 销量 FROM 销售 WHERE (MONTH(sdate) = '你要查的月份数字') GROUP BY 商品名称

　　统计某月商品销量最大的商品前10个商品及销量并按销量排序

　　SELECT DISTINCT TOP 10 商品名称, SUM(价格) AS 产品总价, COUNT(*) AS 销量 FROM 销售 WHERE (MONTH(日期) = '你要查的月份数字') GROUP BY 商品名称 ORDER BY 销量 DESC
