PipelineBuffer Mengirim baris ke propertinya IDTSOutput100IsErrorOut adalah true.
Overload
| DirectErrorRow(Int32, Int32, Int32) |
PipelineBuffer Mengirim baris ke properti IDTSOutput100 yang IsErrorOut benar. |
| DirectErrorRow(Int32, Int32, Int32, Int32) |
PipelineBuffer Mengirim baris ke properti IDTSOutput100 yang IsErrorOut benar. |
DirectErrorRow(Int32, Int32, Int32)
PipelineBuffer Mengirim baris ke properti IDTSOutput100 yang IsErrorOut benar.
public:
void DirectErrorRow(int outputID, int errorCode, int errorColumn);
public void DirectErrorRow (int outputID, int errorCode, int errorColumn);
member this.DirectErrorRow : int * int * int -> unit
Public Sub DirectErrorRow (outputID As Integer, errorCode As Integer, errorColumn As Integer)
Parameter
- outputID
- Int32
ID kesalahan IDTSOutput100 untuk mengirim PipelineBuffer baris.
- errorCode
- Int32
Nomor kesalahan yang terjadi saat memproses baris.
- errorColumn
- Int32
ID PipelineBuffer kolom yang menyebabkan kesalahan.
Contoh
Contoh kode berikut menunjukkan cara mengarahkan baris dalam buffer ke output kesalahan sinkron dengan menggunakan DirectErrorRow metode .
public override void ProcessInput(int inputID, PipelineBuffer buffer)
{
IDTSInput100 input = ComponentMetaData.InputCollection.GetObjectByID(inputID);
/// This code sample assumes the component has 2 outputs, one the default,
/// the other the error output. If the errorOutputIndex returned from GetErrorOutputInfo
/// is 0, then the default output is the second output in the collection.
int defaultOutputID = -1;
int errorOutputID = -1;
int errorOutputIndex = -1;
GetErrorOutputInfo(ref errorOutputID,ref errorOutputIndex);
if (errorOutputIndex == 0)
defaultOutputID = ComponentMetaData.OutputCollection[1].ID;
else
defaultOutputID = ComponentMetaData.OutputCollection[0].ID;
while (buffer.NextRow())
{
try
{
/// TODO: Implement code to process the columns in the buffer row.
/// Ideally, your code should detect potential exceptions prior to them occurring, rather
/// than having a generic try/catch block such as this.
/// However, since the error or truncation implementation is specific to each component
/// this sample focuses on actually directing the row, and not a single error or truncation.
/// Unless an exception occurs, direct the row to the default
buffer.DirectRow(defaultOutputID);
}
catch
{
/// Yes. Has the user specified to redirect the row?
if (input.ErrorRowDisposition == DTSRowDisposition.RD_RedirectRow)
{
/// Yes, direct the row to the error output.
/// TODO: Add code to include the errorColumnID
buffer.DirectErrorRow(errorOutputID, 0, errorColumnID);
}
else if (input.ErrorRowDisposition == DTSRowDisposition.RD_FailComponent || input.ErrorRowDisposition == DTSRowDisposition.RD_NotUsed)
{
/// No, the user specified to fail the component, or the error row disposition was not set.
throw new Exception("An error occurred, and the DTSRowDisposition is either not set, or is set to fail component.");
}
else
{
/// No, the user specified to ignore the failure so
/// direct the row to the default output.
buffer.DirectRow(defaultOutputID);
}
}
}
}
Public Overrides Sub ProcessInput(ByVal inputID As Integer, ByVal buffer As PipelineBuffer)
Dim input As IDTSInput100 = ComponentMetaData.InputCollection.GetObjectByID(inputID)
Dim defaultOutputID As Integer = -1
Dim errorOutputID As Integer = -1
Dim errorOutputIndex As Integer = -1
GetErrorOutputInfo(errorOutputID, errorOutputIndex)
If errorOutputIndex = 0 Then
defaultOutputID = ComponentMetaData.OutputCollection(1).ID
Else
defaultOutputID = ComponentMetaData.OutputCollection(0).ID
End If
While buffer.NextRow
Try
buffer.DirectRow(defaultOutputID)
Catch
If input.ErrorRowDisposition = DTSRowDisposition.RD_RedirectRow Then
buffer.DirectErrorRow(errorOutputID, 0, errorColumnID)
Else
If input.ErrorRowDisposition = DTSRowDisposition.RD_FailComponent OrElse input.ErrorRowDisposition = DTSRowDisposition.RD_NotUsed Then
Throw New Exception("An error occurred, and the DTSRowDisposition is either not set, or is set to fail component.")
Else
buffer.DirectRow(defaultOutputID)
End If
End If
End Try
End While
End Sub
Keterangan
Metode ini digunakan oleh komponen aliran data yang memiliki IDTSOutput100 objek dengan properti diatur IsErrorOut ke true. Ini dipanggil oleh komponen ketika mengalami kesalahan saat memproses baris buffer, dan kapan RD_RedirectRow ditentukan pada input, output, atau kolom.
Berlaku untuk
DirectErrorRow(Int32, Int32, Int32, Int32)
PipelineBuffer Mengirim baris ke properti IDTSOutput100 yang IsErrorOut benar.
public:
void DirectErrorRow(int row, int outputID, int errorCode, int errorColumn);
public void DirectErrorRow (int row, int outputID, int errorCode, int errorColumn);
member this.DirectErrorRow : int * int * int * int -> unit
Public Sub DirectErrorRow (row As Integer, outputID As Integer, errorCode As Integer, errorColumn As Integer)
Parameter
- row
- Int32
Indeks baris yang akan diarahkan ke output kesalahan.
- outputID
- Int32
ID kesalahan IDTSOutput100 untuk mengirim PipelineBuffer baris.
- errorCode
- Int32
Nomor kesalahan yang terjadi saat memproses baris.
- errorColumn
- Int32
ID PipelineBuffer kolom yang menyebabkan kesalahan.
Keterangan
Komponen aliran data memanggil metode ini jika komponen aliran data memiliki IDTSOutput100 objek yang properti masing-masing IsErrorOut diatur ke true. Komponen memanggil metode ini ketika komponen mengalami kesalahan saat memproses baris buffer, dan kapan RD_RedirectRow ditentukan pada input, output, atau kolom.
