Answer 1

You should be able to achieve this using fully qualified names, like:

SELECT * FROM A_Archive.dbo.T
UNION ALL
SELECT * FROM A.dbo.T

depending on whether dbo is the correct scheme. Also you need to make sure the user excuting the select does have the necessary rights on both databases.

Answer 2

If the both databases are on the same server you can simply write this query

SELECT * FROM [DatabaseName].dbo.[tableName]
  UNION ALL
SELECT * FROM [AnotherDatabaseName].dbo.[AnothertableName]

But if these two databases are on different servers you need to consider sp_addlinkedserver to create a server link. read more from this link
