Sql 使用临时表找不到多部分标识符

我有以下填充临时表的查询：

with CTE as
(
select a.accountid as 'myid',
       a.new_mprnnumber, 
       a.new_customernumber,
       b.*, 
       row_number() 
         over (partition by new_customernumber -- add additional partitions as you would group bys
               order by billingPeriodEndDate desc) as r_ord 
from [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] a
inner join bill  b
  on a.new_mprnnumber = b.MPRN
where new_accountstage = 7
and new_accounttype = 2 
)
select *
into #tempCTE
from CTE
where r_ord = 1

update aeb
    set new_invoicenumber = t.invoicenumber
    from [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] aeb join
         #tempCTE t
         on aeb.accountid = t.myid;

在临时表中收集信息后，我希望遍历每条记录，并使用accountid（但使用以下语句）更新主表：

update [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase]
set new_invoicenumber = invoicenumber
where accountid = #tempCTE.myid

我收到一个错误，无法绑定多部分标识符，您知道是什么导致了这个问题吗？

您需要引入临时表：

with CTE as
(
select a.accountid as 'myid',
       a.new_mprnnumber, 
       a.new_customernumber,
       b.*, 
       row_number() 
         over (partition by new_customernumber -- add additional partitions as you would group bys
               order by billingPeriodEndDate desc) as r_ord 
from [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] a
inner join bill  b
  on a.new_mprnnumber = b.MPRN
where new_accountstage = 7
and new_accounttype = 2 
)
select *
into #tempCTE
from CTE
where r_ord = 1

update aeb
    set new_invoicenumber = t.invoicenumber
    from [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] aeb join
         #tempCTE t
         on aeb.accountid = t.myid;

请注意，您不需要临时表。您只需执行以下操作：

with tempCTE as ( . . . )
update aeb
    set new_invoicenumber = t.invoicenumber
    from [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] aeb join
         tempCTE t
         on aeb.accountid = t.myid
    where tempCTE.r_ord = 1

你能从CTE执行select吗？用你正在使用的数据库（大概是SQL Server）标记你的问题。你到底为什么要遍历记录？这是在数据库中几乎不应该做的事情。您已经在CTE中识别了最新的记录。因为花了太长时间，我只是检查它是否在做同样的事情，更新4163帐户花费了13:10分钟。我是否将我的r_ord=1对账单留在那里？我只想用最新的发票更新发票号，列表应该返回accountid，然后我想将其用作update的键yes将r_ord=1作为update语句中的where子句。
