Sharing SQL Server objects

I'm by no means a Sql server expert and need some basic help. I have 2 completely separate sql files attached. For example, File 1.mdf and File 2.mdf. I need to modify data in File 1.mdf based on reference tables in File 2.mdf.

Is it even possible to construct a query using both files?

My original thought was to export the files to MS Access to make the changes but File 1.mdf exceeds the 2 Gbyte Access limit so I'm stuck with how to do this in Sql Server directly.

Ideas anyone?

You can write cross database queries in each database or setup views to access a different database.

In DB1, you can update a table in DB2 like this
Update DB2.dbo.Table1 SET qty=1 WHERE ID=1

In DB2, you can do the same things to update a table in DB1 like this
Update DB1.dbo.tbl SET thiscolumn=1 WHERE ID=1

D'oh? .mdf files are the database file. As long as you don't want to reinvent the wheel and code your own SQL server

So, can you please rephrase your question and tell us what you're trying to do actually?
