Rollback (MDStore Interface)

HinweisHinweis

  Diese Funktion wird in der nächsten Version von Microsoft SQL Server entfernt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie so bald wie möglich das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

The Rollback method of the MDStore interface rolls back a transaction on a database. All changes made to the object subsequent to the initiation of the transaction with the BeginTrans method are voided and the object remains in the state it was in at the time of the beginning of the transaction.

Applies To:clsDatabase

Syntax

object.Rollback

Parameter

  • object
    The database object on which to roll back the transaction.

Hinweise

If the Rollback method is called without first calling the BeginTrans method, an error occurs.

The following code example begins a transaction on the FoodMart 2000 database, processes the Sales and Budget cubes, and rolls back the transaction. Executing the Rollback method for the database restores the Sales and Budget cubes to the state prior to the execution of the BeginTrans method.

    Dim dsoServer As New DSO.Server
    Dim dsoDB As DSO.MDStore
    Dim dsoCube As DSO.MDStore

    ' Connect to the local Analysis server.
    dsoServer.Connect "LocalHost"
    
    ' Open the FoodMart 2000 database.
    Set dsoDB = dsoServer.MDStores("FoodMart 2000")
    
    ' Begin a transaction on the database.
    dsoDB.BeginTrans
    
    ' Create a reference to the Sales cube.
    Set dsoCube = dsoDB.MDStores("Sales")
    
    ' Process the cube, refreshing data.
    dsoCube.Process processRefreshData
    
    'Create a reference to the Budget cube.
    Set dsoCube = dsoDB.MDStores("Budget")
    
    ' Process the cube completely.
    dsoCube.Process processFull
    
    ' Rollback the transaction
    dsoDB.Rollback
