本文介绍了sql中的平均数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 创建 表#temp2 ( salespersonid int , orders int ) 插入 进入#temp2(salespersonid,orders) 选择 1 , 24 union 全部 选择 2 , 24 union all 选择 3 , 48 union 所有 选择 4 , 72 union 所有 选择 5 , 24 union 全部 选择 6 , 18 union all 选择 2 , 48 union 所有 选择 3 , 24 选择 * 来自#temp2 SELECT salespersonid,sum(orders)作为#temp的数字2 group by salespersonid - 现在输出是 1 24 2 72 3 72 4 72 5 24 6 18 现在我需要平均值而不使用with子句。 而且我也不想使用像计数不同的id [即6]。 平均值=总和/数...我不想用这个... 我需要的是 SELECT salespersonid,sum(orders)as number from#temp2 group by salespersonid 我只需要使用AVG功能,group by和sum 。 - 首先我们按salespersonid进行分组 - 然后我们需要平均 - 解决方案 不确定我是否理解正确。但如果我是正确的,您想获得销售人员的平均销售订单数量。正确?如果是这样,你可以这样做: SELECT salespersonid AS SalesPersonId, SUM(订单)AS编号, AVG(订单)AS平均 FROM #temp2 GROUP BY salespersonid - 我得到解决方案, SELECT AVG( NUMBERS) AS FINALAVERAGE FROM ( SELECT SUM(订单) AS 数字 FROM #temp2 GROUP BY salespersonid ) Ť create table #temp2(salespersonid int,orders int)insert into #temp2(salespersonid,orders)select 1,24union all select 2,24union all select 3,48union all select 4,72union all select 5,24union all select 6,18union all select 2,48union all select 3,24select * from #temp2 SELECT salespersonid,sum(orders) as numbers from #temp2group by salespersonid--so now the output is 1 242 723 724 725 246 18Now i need the average without using with clause.And also i dont want to use like count distinct id [that is 6]. Avg= sum/count.. i dont want to use this...What i need is afterSELECT salespersonid,sum(orders) as numbers from #temp2 group by salespersonidI need to use only AVG function , group by and sum. --so first we are doing group by salespersonid--then we need average -- 解决方案 Not sure if I understood correctly. But if I am correct you want to get the average number of sales orders made by a sales person. Correct? If so, you can do like this:SELECT salespersonid AS SalesPersonId,SUM(orders) AS Numbers,AVG(orders) AS Average FROM#temp2GROUP BY salespersonid--I GOT THE SOLUTION,,SELECT AVG(NUMBERS) AS FINALAVERAGE FROM( SELECT SUM(orders) AS Numbers FROM #temp2 GROUP BY salespersonid) T 这篇关于sql中的平均数的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
