Espacio de nombres 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.

Clases

  Clase Descripción
Clase pública BackPressureException The exception that is thrown when the PipelineComponent.IsInputReady and PipelineComponent.GetDependentInputs methods that handle back pressure in the data flow encounter an unexpected error.
Clase pública BlobColumn Defines a column in a data flow buffer that contains data that has a SQL Server data type of text, ntext, or image.
Clase pública BufferDisconnectedException The exception that is thrown when an attempt to access a PipelineBuffer object fails.
Clase pública BufferNotFoundException The exception that is thrown when a PipelineBuffer is not found.
Clase pública CannotCreatePipelineComponentException The exception that is thrown when the data flow cannot create an instance of a Script component.
Clase pública CannotCreateUserComponentException Exception thrown when the Script component cannot instantiate the class that contains the custom code that the developer creates in the Script component. The class is named ScriptMain by default.
Clase pública ColumnIndexOutOfRangeException The exception that is thrown when an attempt to access a buffer column by using an index is outside the bounds of the collection of buffer columns.
Clase pública ColumnIsNullException The exception that is thrown when using a specific data type column access method and the column value is null.
Clase pública ComponentUpgradeFailedException The exception that is thrown when the PerformUpgrade method of a component fails.
Clase pública ComponentVersionMismatchException The exception that is thrown when the component version stored in the package XML is higher than the version of the component installed on the current computer.
Clase pública DoesNotFitBufferException The exception that is thrown when a value that is too large to fit in the data area of a BufferColumn is written to the buffer.
Clase pública DtsPipelineComponentAttribute Contains design-time information about a PipelineComponent object.
Clase pública InputIDToNameMap Represents the input ID to name map.
Clase pública InputNotFoundException The exception that is thrown when the Script Component is unable to find an IDTSInput100 object defined internally by the component.
Clase pública ManagedComponentHost Infraestructura. Represents the host for the DTS managed component.
Clase pública NoCurrentRowException The exception that is thrown when the address of the beginning of a PipelineBuffer row is null.
Clase pública NotOutputBufferException The exception that is thrown when a method that is restricted to Output objects is called on an InputPipelineBuffer.
Clase pública OutputNameMap Represents the output name map.
Clase pública OutputNotFoundException The exception that is thrown by the ScriptComponent when an IDTSOutput100 cannot be found in its IDTSOutputColumnCollection100.
Clase pública PipelineBuffer Provides an in-memory data store containing rows and columns of data.
Clase pública PipelineComponent Defines the base class that is used when developing managed data flow components.
Clase pública PipelineComponentHResultException Exception raised by the Script component when it encounters a COM exception.
Clase pública ReadOnlyVariablesNotAvailableException Exception raised by the Script component when the ReadOnlyVariables collection is not available.
Clase pública ReadWriteVariablesNotAvailableException Exception raised by the Script component when the ReadWriteVariables collection is not available.
Clase pública RowIndexOutOfRangeException The exception that is thrown when an invalid index is supplied when accessing a row in a PipelineBuffer.
Clase pública ScriptBuffer Serves as the base class for the read-only classes representing the input and the outputs that are generated by the Script component in the BufferWrapper project item in a Script component project.
Clase pública ScriptComponent Serves as the base class for the read-only UserComponent class generated by the Script component in the ComponentWrapper project item in a Script component project.
Clase pública ScriptComponent.ScriptComponentEvalContext Represents the script components evaluator context.
Clase pública ScriptComponentHost Infraestructura. Represents the host for the script component.
Clase pública ScriptingLanguageNotFoundException The exception that is thrown by the Script component when the scripting language is not found.
Clase pública SSISScriptComponentEntryPointAttribute Infraestructura. Represents the SSIS script component entry point attribute.
Clase pública UnsupportedBufferDataTypeException The exception that is thrown when assigning a value to a buffer column that contains the incorrect data type.
Clase pública UnsupportedDataRecordTypeException The exception that is thrown when an unsupported parameter value is passed to the DataRecordTypeToBufferType method.
Clase pública UnsupportedValueTypeForTextStreamColumnException The exception that is thrown when the type of the value that is being assigned to a column in a PipelineBuffer is not a string or byte array.
Clase pública VSTAComponentScriptingEngine Infraestructura. Represents the VSTA component scripting engine.
