Joe拥有一家全球DVD租赁店。他在全球各地都有商店。他每个月都喜欢通过查找他的库存百分比来确定他的商店中的设备是否是最新的，并且状态为“当前”，＃34; ＆＃34;需要更新，＆＃34;和＆＃34;必须去＆＃34;对于每个地区。这有助于确保他的客户在他的商店中获得最佳体验。

比尔，他的助手，想要建立一个SQL查询，向Joe展示每个地区的设备百分比及其状态。在他之前的那个人使用excel来做这个，但比尔认为SQL然后一个SSRS报告允许乔选择他想要查看哪个区域会给他留下深刻印象。随着报告中的年度进展，他希望将其从几个月动态过渡到几个季度。这是比尔迄今为止能够提出的：

将它与之前的excel进行比较，一切都是正确的，除了北美之外，他的SSRS完全正常运行，北美的百分比略有下降。他认为北美次区域的加权平均值会解决这个问题，以确保百分比正确，因为有些次区域比其他次区域更大。

Bill如何计算北美每个地区的加权平均值？

1 个答案:

答案 0 :(得分：0)

这个查询看起来有点像狗早餐。 主要问题：

    SELECT DISTINCT查询中不需要
  1. GROUP BY，因为值已经不同。 如果DISTINCT中的数据未规范化，我可以了解COUNTS和TOT查询中TABLEIMPORT的使用情况。
  2. 解释查询意图的评论总和。
  3. 变量/别名命名非常差。

    4. 我怀疑第一个查询的问题在于：

    QTRMNTH as (
select distinct
q.Quarter  [Month]
,q.Percents [Percents]
,d.[Equipment Status]
,d.Quarter
,d.Year
,o.SelectRegion
from data d
     inner join OWN o on o.[Region] = d.[Region]
     inner join QUARTERS q on q.Quarter = d.Quarter and q.year = d.Year and q.[Equipment Status] = d.[Equipment Status]
where d.[Month] < DATEADD(qq, DATEDIFF(qq, 0, GETDATE()) - 1, -1) and   d.[Month] > dateadd(MONTH,-12,GETDATE())

    我认为上面的代码应该返回每个＆＃34;更大区域的季度结果＆＃34; [SelectRegion]基于月度数据（data）。如果是这种情况，则需要删除DISTINCT并添加GROUP BY。

    我认为从所有其他查询中删除DISTINCT以便能够发现其他隐藏问题也很有帮助。
