Question

我的查询返回一个数据透视表，第一列（nummnth）包含1月，2月，3月等文本值，如01,02,03。问题是排序是01,03,02而不是01， 02,03。

我怎么能解决这个问题？

查询是：

   select [nummnth] ,[mnth],[Business Fixed Score],[Business Fixed 
   Sessions],[Business Mobile Score],[Business Mobile Sessions],[Business 
   Merged Score],[Business Merged Sessions] from (Select [nummnth],
   [Mnth],C.* from (
   SELECT [Service],nummnth,mnth,b.A2 as [User_Score],b.A2_Sessions as 
   [Sessions_Count] FROM [QTDB].[dbo].[QTD_BOX_BUS_MERGED_CP] as [b] where 
   YR=2017 
    and [service] = 'Business Fixed' and Agent='ANAME'
   Union 
   SELECT [Service],nummnth,mnth,b.A2 as [User_Score],b.A2_Sessions as 
   [Sessions_Count] 
   FROM [QTDB].[dbo].[QTD_BOX_BUS_MERGED_CP] as [b] where YR=2017 and 
   [service] = 'Business Mobile' and Agent='ANAME'
   UNION all 
   SELECT 'Business Merged' as [Service] ,nummnth,mnth,b.A2 as 
   [User_Score],b.A2_Sessions as [Sessions_Count]  
   FROM [QTDB].[dbo].[QTD_BOX_BUS_AGENT_MNTH_MERGED] as [b]  where YR=2017 
   and Agent='ANAME')  A 
   Cross Apply (Values (A.[Service]+' Score',
   cast(A.[User_Score] as float)),(A.[Service]+' Sessions',cast(A.
   [Sessions_Count] as float))) C (Item,Value)) R Pivot (
   sum(Value) For [Item] in ([Business Fixed Score],
   [Business Fixed Sessions],
   [Business Mobile Score],[Business Mobile Sessions],
   [Business Merged Score],[Business Merged Sessions])) PV

在SQL-Server 中没有隐含的顺序!! 无，从不...

你甚至不能说问题在于排序是01,03,02而不是01,02,03。下一次调用它可能以不同的方式返回。

确保订单的唯一方法是在最外层的查询上ORDER BY！

只需添加ORDER BY [nummnth]作为最后一行并检查结果。
