Sql 使用临时表插入存储过程

我有一个视图，我正试图在SQL中声明为临时表。我正在声明它，但我得到的错误是必须声明标量变量@temp。我不太清楚为什么会发生这种错误。下面是我的存储过程代码。最终目标是能够在存储过程中的插入上使用此临时表的值

USE [DATABASE]

SET ANSI_NULLS OFF

@temp是一个表变量，因此如果使用该变量中的列，则需要将该变量放入from子句中。因此，您的最后一条insert语句应该如下所示：

insert into tblClaimComponents values 
select 'CR', intClaimNum, '999999', 'Description', chrCvgCode .... --Other values here
from @temp

为什么需要插入到表变量中，然后从该变量插入到tblClaimComponents，而不是直接插入？为什么需要在过程循环中执行此操作，而不是基于集合？
