TransferPercentComplete Event
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The TransferPercentComplete event occurs after SQL Distributed Management Objects (SQL-DMO) completes schema or data copy for a Microsoft SQL Server component referenced by the Transfer object.
Sintassi
Private Subobject_TransferPercentComplete(Message as String, Percent as Long)
Parts
object
Expression that evaluates to an object in the Applies To list.Message
String that contains descriptive message text.Percent
Long integer representation of a percentage value. The value is the percent of processing complete scaled by 100. For example, a process seven percent complete reports the value 7.
Prototype (C/C++)
HRESULT TransferPercentComplete(SQLDMO_LPCSTR szMessage,
long Percent);
Osservazioni
When using the Transfer method of the Database object, SQL-DMO calculates percentage completion after a component is copied. Component copy can be implemented by simple, non-time-intensive tasks such as creation of schema, or can require time-intensive tasks such as the copy of a large amount of data.
The TransferPercentComplete event is raised once for every component referenced by the Transfer object. SQL-DMO attempts to weight the value provided in the Percent argument of the event handler to reflect the time needed to re-create a component on the target database.
