Sql server 2008 SSIS-在多个并行任务中使用表变量

我正在使用以下逻辑编写T-SQL脚本：

declare @tbl table(id int)

insert @tbl select distinct id -- <-- this takes about 3 minutes
  from link1.some_table
  where <some_conditions>

insert some_local_table(field1, field2, fieldN)  -- <-- this takes about 30 minutes
  select field1, field2, fieldN
  from link2.some_table
  where id in (select id from @tbl)
    and <some conditions>

insert some_OTHER_local_table(field1, field2, fieldN) -- <-- another 30 minutes
  select field1, field2, fieldN
  from link2.some_OTHER_table
  where id in (select id from @tbl)
    and <some conditions>

insert some_YET_OTHER_local_table(field1, field2, fieldN) -- <-- another 30m, and so on
  select field1, field2, fieldN
  from link2.some_YET_OTHER_table
  where id in (select id from @tbl)
    and <some conditions>

declare@tbl表（id int）
insert@tbl select distinct id--您不能在每个任务中使用子查询而不是表变量吗

 insert some_local_table(field1, field2, fieldN)  
 select field1, field2, fieldN
 from link2.some_table
 where id in (
      select id   
      from link1.some_table
      where <some_conditions>
   )
 and <some conditions>

。。。然后

declare @tbl table(id int)

insert @tbl select distinct id -- <-- this takes about 3 minutes
  from link1.some_table
  where <some_conditions>

insert some_OTHER_local_table(field1, field2, fieldN) -- <-- another 30 minutes
  select field1, field2, fieldN
    from link2.some_OTHER_table
   where id in (select id from @tbl)
     and <some conditions>

declare@tbl表（id int）
插入@tbl select distinct id——谢谢Ann L。在各个任务之间复制变量肯定会奏效。然而，有一个小风险，即数据将在link1.0表中发生变化，导致查询之间的结果不一致。现在，在本地表而不是本地变量中缓存数据是很诱人的（我们在本地得到一个静态@tbl数据快照），但是我害怕在链接的服务器表和本地表之间编写一个连接子句-远程查询已经非常复杂（它实际上是一个视图）。我会尝试一下，如果它有效，我会把你的答案标记为正确。再次感谢！可以使用全局临时表而不是表变量。甚至是在包的末尾截断的永久表。

insert some_OTHER_local_table(field1, field2, fieldN) -- <-- another 30 minutes
  select field1, field2, fieldN
    from link2.some_OTHER_table
   where id in (select id from @tbl)
     and <some conditions>
