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