Constructors
| AstCdcSourceNode(IFrameworkItem) | Initializes a new instance of the AstCdcSourceNode class with the specified parent node. |
Fields
| ScopedNamePrefixBackingStore | |
| IsScopeImported |
Properties
| CaptureInstance | Specifies the name of the CDC capture instance that should be used for the table specified in the Table property. |
| CaptureInstanceDefaultValue | Gets the default value for the CaptureInstance property |
| Columns | This is a collection of mapping nodes from source columns prior to sending them to the output path. |
| Connection | Specifies the ADO.NET connection that should be used to connect to the CDC-enabled database. |
| ErrorPath | The output path that receives any rows that are produced from error conditions with the CDC retrieval |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| IncludeReprocessingIndicatorColumn | Specifies whether or not the special output column __$reporcessing should be included in the output rows for this component. This column will have a value of true for rows that are being reprocessed - i.e. those rows in a processing range that overlaps with the range of the initial load or a previous run that ended in error. The default is true. |
| IncludeReprocessingIndicatorColumnDefaultValue | Gets the default value for the IncludeReprocessingIndicatorColumn property |
| OutputPath | The output path that receives any rows that are produced from the CDC-enabled table |
| ProcessingMode | Specifies the CDC processing mode that should be used for this CDC source. Acceptable values are provided in the CdcProcessingMode enumeration. |
| ProcessingModeDefaultValue | Gets the default value for the ProcessingMode property |
| StateVariable | Specifies the package variable that is used to store the CDC state for the current context. |
| Timeout | The number of seconds before the command times out. Zero indicates an infinite time-out. The default value is 30. |
| TimeoutDefaultValue | Gets the default value for the Timeout property |
| VisibleVariables | Gets a collection of all variable nodes that are available to be used by this transformation. It includes variables defined by this transformation and any tasks/packages that contain this transformation |
| PreferredOutputPath | Gets the preferred output path for the transformation. This output path will support automatic connections to single-input transformations that directly follow in the Biml code |
| DataflowInputs | Gets a collection of all dataflow input paths for this transformation |
| DataflowOutputs | Gets a collection of all dataflow output paths for this transformation |
| ValidateExternalMetadata | This value specifies whether the data flow transformation is validated against columns that originated in external data sources. When server assets such as tables and stored procedures are created during processing, ValidateExternalMetadata is normally set to False, which prevents validation from completing at compile time. |
| LocaleId | This value specifies which locale is used by the dataflow task. |
| ErrorHandling | This value specifies how errors are handled by default in columns processed by the component. This can be overriden at the component or column level for specific cases. |
| DataflowOverrides | Provides a collection of objects to override properties of the component, its input paths, its output paths, and its consituent dataflow columns. |
| ValidateExternalMetadataDefaultValue | Gets the default value for the ValidateExternalMetadata property |
| LocaleIdDefaultValue | Gets the default value for the LocaleId property |
| ScopedName | Gets the scoped name which can be used to uniquely identify this object among other objects of its type |
| SymbolTable | Gets a reference to the symbol table that stores a reference to this and all other named objects in the project |
| SsisSafeScopedName | Returns a version of the ScopedName that has been cleaned of invalid characters for SSIS. |
| SsisSafeName | Returns a version of the Name that has been cleaned of invalid characters for SSIS. |
| Name | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. |
| References | Gets collection of FrameworkItemReference objects, which track rich information about the properties that hold references to this node. |
| NameDefaultValue | Gets the default value for the Name property |
| Guid | |
| Annotations | This is a collection of annotation items that can be used to specify documentation, tags, or other information. Annotations are particularly useful for storing information about nodes that can be used by BimlScript code. |
| ObjectTag | This property provides a general purpose storage mechanism for .NET objects to be associated with AstNode objects. It supplements the annotation system, which is intended for use with string-based metadata. |
| BimlFile | This value specifies the BimlFile in which the Biml code that defines AstNode resides. |
| ItemLabel | Gets a label that can be used to identify this node |
| ParentItem | This value specifies the parent of the current node. All nodes must have a valid parent in the Biml framework, except for the root node. |
