Detaches a SQL Server Express geodatabase (.mdf).
Removes all references to the geodatabase from the database server. It does not delete the data file (.mdf). Once detached, you can attach the data file to another SQL Server Express instance.
The .mdf file and the full-text catalog for the database are in the directory in which you initially created the geodatabase.
When copying a detached geodatabase to another server, you do not need to copy the .ldf file. The Attach Database tool creates a new .ldf. You must copy the full-text catalog with the database (.mdf). For SQL Server 2008 Express, the full-text catalog is in the .mdf file. For the full-text catalog to transfer properly, the database server to which you move the geodatabase must also be set up to use SQL Server Full-Text Search.
The geodatabase must not be in use by another process during detach.
You must have Server Administrator privileges to detach a geodatabase.
The geodatabase to detach from an instance of SQL Server Express.
