Замечания

Изменения текста

The data and transaction log files of a database can be detached and then reattached to the same or another instance of SQL Server. Detaching and attaching a database is useful if you want to change the database to a different instance of SQL Server on the same computer, or if you want to move the database.

'Detach the AdventureWorks database.
srv.DetachDatabase("AdventureWorks", False, False)

'Display information about the detached database.
Dim d As DataTable
Datastr = "C:\Program Files\Microsoft SQL Server"

Logstr = "C:\Program Files\Microsoft SQL Server"
Logstr = datastr + "\MSSQL.1\MSSQL\Data\AdventureWorks_Log.ldf"
