Not at the same time.

You can change your Connection object to open one or the other database and then use your command on the opened connection.

If you want to refer to data from two different dbs using a single SQL command, you could do this in a stored procedure.

If you are talking about SQL server, you can access to different databases like this:

select * from db1.dbo.table1, db2.dbo.table1

i.e. use dbname.user.tablename

For different servers, may be you need to open two diff. recordsets and do it.

In Sql server you can write sql using use database.owner.table name in from clause

& in Oralce you can creat link to use other database(user) in from clause. Please see the hel to how to create link of other database(user). That link can use from clause, so you can use more then one  database in a single sql statment.

With SQL Server 7 and above you can create linkedservers and remote servers which can be used in distributed transactions. With Access also you can use the IN clause to affect data in other access databases.

As I said earlier (and emoreau did just now) create a linked server and you can use data from both in the same transaction.
