尝试使用别名 Transact Sql 时出现无效的列名错误

Question

我打算做的是有一个订单剩余列，这将是以下计算的结果： [orderedvalue] - [totaljobvalue]

select [orderedvalue] = sum([ordervalue]), 
       jobtype,
       [totaljobvalue] = (select sum([total value]) 
                          from job 
                          where jobType = quotetrackerorders.jobType 
                          and reference like '%40330%')
from quotetrackerorders
where quoteref like '%40330%'
group by jobtype

我试过下面的代码：

select [orderedvalue] = sum([ordervalue]), 
       jobtype,
       [totaljobvalue] = (select sum([total value]) 
                          from job 
                          where jobType = quotetrackerorders.jobType 
                          and reference like '%40330%'),
       [orderremaining] = [orderedvalue] - [totaljobvalue]
from quotetrackerorders
where quoteref like '%40330%'
group by jobtype

但是这不起作用，因为它无法将任何别名识别为列...我可以做些什么来实现以下结果：

• JobType = 壁画
• Orderedvalue = 311654（示例值）
• TotalJobvalue = 3446（示例值）
• OrderRemaining = 64654（示例值）

您知道如何让 SQL 将这些别名识别为列吗？

考虑以下

Select A.*
      ,SomeName = [orderedvalue] - [totaljobvalue]
 From (
        Select [orderedvalue] = sum([ordervalue])
              , jobtype
              , [totaljobvalue] = (select sum([total value]) 
                                   from job 
                                   where jobType = quotetrackerorders.jobType 
                                   and reference like '%40330%')
        from quotetrackerorders
        where quoteref like '%40330%'
        group by jobtype
