Propiedades

  Nombre Descripción
Propiedad pública AreInputColumnsAssociatedWithOutputColumns Infraestructura. Gets whether the input columns are associated with output columns.
Propiedad pública Buffer Gets the ID of a PipelineBuffer that is allocated for an IDTSInput100 object and provided to the component in the ProcessInput method.
Propiedad pública BufferBase Infraestructura. Gets the abstract base class of the IDTSInput100.
Propiedad pública Component Gets the IDTSComponentMetaData100 object of an IDTSInput100 object.
Propiedad pública CustomPropertyCollection Gets the IDTSCustomPropertyCollection100 object of an IDTSInput100 object.
Propiedad pública Dangling Gets or sets a value that notifies the data flow engine that the input can be unattached.
Propiedad pública Description Gets or sets the description of an IDTSInput100 object.
Propiedad pública ErrorOrTruncationOperation Gets or sets a String that specifies the types of errors or truncations that can occur while processing a PipelineBuffer row.
Propiedad pública ErrorRowDisposition Gets or sets a value from a DTSRowDisposition enumeration that specifies how the component will handle error conditions that occur when processing a row from a PipelineBuffer object.
Propiedad pública ExternalMetadataColumnCollection Gets the collection of columns that reflects the columns in an external data source, which are used to validate an IDTSInputColumnCollection100 when the component is not connected to the external data source.
Propiedad pública HasSideEffects Gets or sets a value that indicates whether a data flow component should be removed or remain in the execution plan of a data flow task when its output is not attached to a downstream component and when the RunInOptimizedMode property of the Data Flow task is true.

Comentarios

The IDTSInput100 object represents a connection point between two components, and, when connected to the IDTSOutput100 of an upstream component, establishes the flow of data between components. A connection between an IDTSInput100 and an IDTSOutput100 is established through the IDTSPath100 object. The input represents the EndPoint property of the IDTSPath100 object.

At design time, the columns in the IDTSOutputColumnCollection100 of the output that the input is connected to are selected for use by the component. These columns are then available to the component during component execution.

Ejemplos

The following code example demonstrates a component adding an input to its collection in the ProvideComponentProperties method.

using System;
using Microsoft.SqlServer.Dts.Pipeline;
public class DtsSampleComponent : PipelineComponent
{ 
public override void ProvideComponentProperties()
{
IDTSInput100 input = ComponentMetaData.InputCollection.New();
input.Name = "SampleComponentInput0";
}
}
Imports System 
Imports Microsoft.SqlServer.Dts.Pipeline 

Public Class DtsSampleComponent 
Inherits PipelineComponent 

 Public Overloads Overrides Sub ProvideComponentProperties() 
   Dim input As IDTSInput100 = ComponentMetaData.InputCollection.New 
   input.Name = "SampleComponentInput0" 
 End Sub 
End Class
