Spazio dei nomi Microsoft.SqlServer.Dts.Pipeline

The Microsoft.SqlServer.Dts.Pipeline namespace contains managed classes that are used to develop managed data flow components. It contains the PipelineComponent class, which is the base class for managed data flow components, and the PipelineBuffer class, which is the managed implementation of the IDTSBuffer100 interface. The PipelineBuffer class marshals data flow buffers between the COM data flow engine and managed data flow components.

Classi

  Classe Descrizione
Classe pubblica BlobColumn Defines a column in a data flow buffer that contains data that has a SQL Server data type of text, ntext, or image.
Classe pubblica BufferDisconnectedException The exception that is thrown when an attempt to access a PipelineBuffer object fails.
Classe pubblica BufferNotFoundException The exception that is thrown when a PipelineBuffer is not found.
