AssignmentDiag Property

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 AssignmentDiag property enables ISO standard behavior for NULL in aggregate, data truncation, divide-by-zero, and arithmetic overflow errors.

Parts

• object

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetAssignmentDiag(LPBOOL pRetVal);
HRESULT SetAssignmentDiag(BOOL NewValue);

Osservazioni

If TRUE, ISO standard behavior is enabled. If NULL is involved in an aggregate, data is truncated on an INSERT or UPDATE statement execution, or a divide-by-zero or arithmetic overflow occurs, these events follow:

• The statement is stopped.

• Any transactions are rolled back.

• An error is returned to the client.

If FALSE, ISO behavior is disabled. If NULL is returned for an affected column or data is truncated on an INSERT or UPDATE, these events follow:

• Transactions are not rolled back.

• The client receives either an error, success with information, or a success return code.
