Namespace 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.

Classes

	Classe	Descrição
	BlobColumn	Defines a column in a data flow buffer that contains data that has a SQL Server data type of text, ntext, or image.
	BufferDisconnectedException	The exception that is thrown when an attempt to access a PipelineBuffer object fails.
	BufferNotFoundException	The exception that is thrown when a PipelineBuffer is not found.
	CannotCreatePipelineComponentException	The exception that is thrown when the data flow cannot create an instance of a Script component.
	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.
	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.
	ColumnIsNullException	The exception that is thrown when using a specific data type column access method and the column value is null.
	ComponentUpgradeFailedException	The exception that is thrown when the PerformUpgrade method of a component fails.
	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.
	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.
	DtsPipelineComponentAttribute	Contains design-time information about a PipelineComponent object.
	InputNotFoundException	The exception that is thrown when the Script Component is unable to find an IDTSInput100 object defined internally by the component.
	ManagedComponentHost	Infraestrutura.
	NoCurrentRowException	The exception that is thrown when the address of the beginning of a PipelineBuffer row is null.
	NotOutputBufferException	The exception that is thrown when a method that is restricted to Output objects is called on an InputPipelineBuffer.
	OutputNotFoundException	The exception that is thrown by the ScriptComponent when an IDTSOutput100 cannot be found in its IDTSOutputColumnCollection100.
	PipelineBuffer	Provides an in-memory data store containing rows and columns of data.
	PipelineComponent	Defines the base class that is used when developing managed data flow components.
	PipelineComponentHResultException	Exception raised by the Script component when it encounters a COM exception.
	ReadOnlyVariablesNotAvailableException	Exception raised by the Script component when the ReadOnlyVariables collection is not available.
	ReadWriteVariablesNotAvailableException	Exception raised by the Script component when the ReadWriteVariables collection is not available.
	RowIndexOutOfRangeException	The exception that is thrown when an invalid index is supplied when accessing a row in a PipelineBuffer.
	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.
	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.
	ScriptComponentHost	Infraestrutura.
	ScriptingLanguageNotFoundException	The exception that is thrown by the Script component when the scripting language is not found.
	SSISScriptComponentEntryPointAttribute	Infraestrutura.
	UnsupportedBufferDataTypeException	The exception that is thrown when assigning a value to a buffer column that contains the incorrect data type.
	UnsupportedDataRecordTypeException	The exception that is thrown when an unsupported parameter value is passed to the DataRecordTypeToBufferType method.
	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.
	VSTAComponentScriptingEngine	Infraestrutura.

Enumerações

	Enumeração	Descrição
	ComponentType	Specifies the three types of data flow components.
	PipelineBufferMode	Contains values used to identify a PipelineBuffer as an input or output buffer.
