You can use the Shrink method to reduce the size of the files that make up the database manually. The data is stored more densely and unused pages are removed. Alternatively, you can shrink the database automatically at intervals by setting the AutoShrink option.

只有 Microsoft .NET Framework 2.0 版支援此命名空間、類別或成員。

範例

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")

'Shrink the database without truncating the log.
db.Shrink(20, ShrinkMethod.NoTruncate)

'Truncate the log.
db.TruncateLog()
