How do I write a series of SQL Server SELECT statements that compare tables in two databases with variables for the db names?

I want to write something like this

declare @db1 nvarchar(100);
declare @db2 nvarchar(100);

select id from [@db1]..MyTable t1 INNER JOIN [@db2]..MyTable t2 on [t1].id=[t2].id

but clearly SQL Server doesn't like the database names in variables - how can I achieve what I am trying to do?

I'm on but I'd like it as generic as possible for versions:
Microsoft SQL Server 2012 - 11.0.5058.0 (X64)
