//Array passed in the first packetPutBulk(Packet: IDtBulkPacket): Boolean;
Packet - packet with data for export.
The PutBulk method exports specified data packet in data consumer.
Executing the example requires the Data.xls file in the disk C root directory.
Sub Main;
Var
ExcelConsumer: IDtExcelConsumer;
Fields: IDtFieldDefinitions;
Field: IDtFieldDefinition;
v, v1: Array;
Pack: IDtBulkPacket;
Begin
//Array passed in the first packet
//Array passed in the second packet
ExcelConsumer := New DtExcelConsumer.Create;
ExcelConsumer.File := "c:\Data.xls";
ExcelConsumer.HasHeader := True;
ExcelConsumer.DriverVersion := "Excel 8.0";
ExcelConsumer.Table := "Sheet1";
Fields := ExcelConsumer.Fields;
Field := Fields.Add;
Field.DataType := DbDataType.String;
Field.Name := "Name";
Field := Fields.Add;
Field.DataType := DbDataType.Integer;
Field.Name := "Identifier";
Field := Fields.Add;
Field.DataType := DbDataType.Float;
Field.Name := "Value";
ExcelConsumer.Open;
Pack := New DtBulkPacket.Create;
Pack.FailPolicy := DatasetFailPolicy.Rollback;
//First packet
Pack.Data := v;
ExcelConsumer.PutBulk(Pack);
If Not Pack.Successful Then
Debug.WriteLine("Error during packet export");
Debug.WriteLine("Entries are not exported: " + Pack.FailedRows.ToString);
Else
Debug.WriteLine("Packet export is successfully completed");
End If;
//Second packet
Pack.Data := v1;
ExcelConsumer.PutBulk(Pack);
If Not Pack.Successful Then
Debug.WriteLine("Error during packet export");
Debug.WriteLine("Entries are not exported: " + Pack.FailedRows.ToString);
Else
Debug.WriteLine("Packet export is successfully completed");
End If;
ExcelConsumer.Close;
End Sub Main;
After executing the example a new data consumer, that exports data in Excel file, is created. Values of two arrays are in turns written in file. If any error appears during rows export changes are undone. Information about export results is displayed in the development environment console.
