例

以下のコード例は、 DirectErrorRow メソッドを用いてバッファ内の行を同期エラー出力に誘導する方法を示しています。

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);

注釈

この方法は、IsErrorOutプロパティがtrueに設定されたオブジェクトを持つIDTSOutput100オブジェクトを持つデータフローコンポーネントで使われます。 コンポーネントがバッファ行を処理する際にエラーに遭遇した際、また入力、出力、または列で RD_RedirectRow が指定されている場合に呼び出されます。

public:
 void DirectErrorRow(int row, int outputID, int errorCode, int errorColumn);

public void DirectErrorRow(int row, int outputID, int errorCode, int errorColumn);

Public Sub DirectErrorRow (row As Integer, outputID As Integer, errorCode As Integer, errorColumn As Integer)

注釈

データフローコンポーネントがこのメソッドを呼び出すのは、そのオブジェクトが IDTSOutput100 個のオブジェクトを持ち、それぞれの IsErrorOut プロパティが trueに設定されている場合です。 コンポーネントはバッファ行を処理する際にエラーに遭遇し、入力、出力、または列で RD_RedirectRow が指定されている場合にこのメソッドを呼び出します。
