Answer 1

You can use IN:

SELECT t1.*, t2.* 
FROM T1 
INNER JOIN 
(SELECT * FROM atable 
IN 'C:\Docs\DB2.mdb') t2
ON t1.ID=t2.ID

EDIT:

sc = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\docs\other.mdb"
cn.open sc

s="SELECT * FROM t1 INNER JOIN " _
& "[MS Access;PWD=databasePWD;DATABASE=C:\docs\db.mdb].t2 ON t1.ID=t2.ID"

rs.Open s, cn

EDIT 2:

You can use the aliases to identify which database a field is from:

s="SELECT * FROM table1 t INNER JOIN " _
& "[MS Access;PWD=databasePWD;DATABASE=C:\docs\db.mdb].m ON t.ID=m.ID"

 msgbox rs.fields("m.code") & " " & rs.fields("t.code")

EDIT 3

Or you can add a virtual field:

 SELECT 1 AS "DB", Field, Field FROM  ...
 UNION ALL
 SELECT 2 AS "DB", Field, Field FROM

UNION ALL is usually faster.
