備註

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.

Visual Basic

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
Dim owner As String
Dim logstr as String
Dim datastr as String
owner = srv.Databases("AdventureWorks2012").Owner

'Detach the AdventureWorks2012 database.
srv.DetachDatabase("AdventureWorks2012", False, False)

'Display information about the detached database.
Dim d As DataTable
Datastr = "C:\Program Files\Microsoft SQL Server"
Datastr = datastr + "\MSSQL10_50\MSSQL\Data\AdventureWorks2012_Data.mdf"
Logstr = "C:\Program Files\Microsoft SQL Server"
Logstr = datastr + "\MSSQL10_50\MSSQL\Data\AdventureWorks2012_Log.ldf"
d = srv.DetachedDatabaseInfo(datastr)
Dim r As DataRow
Dim c As DataColumn
For Each r In d.Rows
    Console.WriteLine("==========================")
    For Each c In r.Table.Columns
        Console.WriteLine(c.ColumnName + " = " + r[c].ToString)
    Next
Next

'Check whether the file is a detached primary file.
Console.WriteLine(srv.IsDetachedPrimaryFile(datastr))

'Attach the database
Dim sc As StringCollection
sc = New StringCollection
sc.Add(datastr)
sc.Add(logstr)
srv.AttachDatabase("AdventureWorks2012", sc, owner, AttachOptions.None)
