Create view across multiple databases

Question

I have two databases; 1 is a live database for daily data input and the other is an archival DB for older data.

How can I create a view which gets data from both dat

Answer 1

Not sure if you need a UNION or a JOIN, but in either case you can just use a three-part name for the object in the other database:

USE database1;
GO
CREATE VIEW dbo.MyView
AS
    SELECT columns FROM dbo.LocalTable
    UNION ALL
    SELECT columns FROM database2.dbo.RemoteTable;
GO
