How to use variables in different Go batch in sql server

Question

I have a dataset containing query like this.

SQL

if @Type = 2
begin
	exec Sp_Test1@cid
;
with result as(select * from Table1 where id=@aid)
select id from result;

end

go

exec Sp_Test2@aid

select * from Table1 where id= @aid

For some reasons I have to call the Sp_Test2 only inside that go.
It shows an error that @aid is not declared.

But @aid is a parameter of my SSRS report and is accessible inside that if condition.
Please help me.
Thanks

Why would you use GO anyway?

You can't use variables across GO: https://msdn.microsoft.com/en-us/library/ms188037.aspx[^] - it effectively starts a new SQL "session".

"The scope of local (user-defined) variables is limited to a batch, and cannot be referenced after a GO command."

You could enable SQLCMD mode:

SQL

:setvar myvar 10 declare @aid int = $(myvar); select @aid go declare @aid int = $(myvar); select @aid

Or simply:

SQL

:setvar myvar 10 select $(myvar) go select $(myvar)

This is an other approach:

SQL

declare @aid int = 10
create table #vars(aid int)
insert into #vars values(@aid)

select @aid

go
declare @aid int
select @aid = aid from #vars
select @aid

[Update] SQLCMD mode is not available in ReportingServices
