SqlCeEngine.Shrink Method

  • Artigo

Reclaims wasted space in the SQL Server Compact Edition database by moving empty pages to the end of the file, and then truncating the file.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

Syntax

'Declaration
Public Sub Shrink
'Usage
Dim instance As SqlCeEngine

instance.Shrink

public void Shrink ()

public:
void Shrink ()

public void Shrink ()

public function Shrink ()

Not applicable.

Remarks

Unlike the Compact method, the Shrink method does not create a temporary database file. Instead, all empty and unallocated pages are moved to the end of the file and are then truncated, reducing the overall database size.

You can configure a database to automatically shrink by setting the AutoShrink property on the database.

Example

Dim engine As New SqlCeEngine("Data Source = AdventureWorks.sdf")
engine.Shrink()

SqlCeEngine engine = new SqlCeEngine("Data Source = AdventureWorks.sdf");
engine.Shrink();
