TFDExecuteErrorEvent = procedure (ASender: TObject; ATimes, AOffset: LongInt;
AError: EFDDBEngineException; var AAction: TFDErrorAction) of object;

C++

typedef void __fastcall (__closure *TFDExecuteErrorEvent)(System::TObject* ASender, System::LongInt ATimes, System::LongInt AOffset, Firedac::Stan::Error::EFDDBEngineException* AError, Firedac::Stan::Intf::TFDErrorAction &AAction);

Description

TFDExecuteErrorEvent is the function type for an OnExecuteError event.

TFDExecuteErrorEvent has the following parameters:

Parameter	Meaning
ASender	The reference to the dataset.
ATimes	The current Array DML size. If the full operation is split into several small operations (on Firebird, for example), ATimes may be different from the ATimes parameter value of the Execute method.
AOffset	The current Array DML offset. If there are skipped erroneous rows or the full operation is split into several small operations (on Firebird, for example), AOffset may be different from the AOffset parameter value of the Execute method.
AError	The original DBMS returned error. Check AError.Errors[i].RowIndex for the index of the erroneous row in the parameters array.
AAction	The action dataset should take place after it returns from the event handler.
