Description
Applies updates received from a client dataset, using a specified provider.
Datasnap.Win.MtsRdm.TMtsDataModule.AS ApplyUpdates inherits from Datasnap.DataBkr.TRemoteDataModule.AS_ApplyUpdates. All content below this line refers to Datasnap.DataBkr.TRemoteDataModule.AS_ApplyUpdates.
Applies updates received from a client dataset, using a specified provider.
AS_AS_ApplyUpdates writes client updates to a dataset or database server. ProviderName specifies the name of the provider component that manages the update operation. Delta is a Variant containing the updated, inserted, and deleted records to write to the database. MaxErrors indicates the maximum number of errors to permit before rolling back the update operation; ErrorCount returns the actual number of errors encountered during the update operation. OwnerData is information supplied by the client application in a BeforeAS_ApplyUpdates event handler and returned to the client application in an AfterAS_ApplyUpdates event handler. It is passed to the provider's BeforeApplyUpdates event handler and returned from the provider's AfterApplyUpdates event handler.
AS_AS_ApplyUpdates The AS_ApplyUpdates_result parameter returns a Variant that is a data packet containing all the records that could not be applied.
Note: Applications can only call the protected AS_AS_ApplyUpdates method using the TRemoteDataModule interface. To apply updates directly in code from the application server, use the provider component's AS_ApplyUpdates method.
