Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| CaptureInstance | String | Specifies the name of the CDC capture instance that should be used for the table specified in the Table property. This is a required property | |
| ConnectionName | AstAdoNetConnectionNode | Specifies the ADO.NET connection that should be used to connect to the CDC-enabled database. This is a required reference to an existing definiton. | |
| Name | String | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. This is a required property | |
| StateVariableName | AstVariableNode | Specifies the package variable that is used to store the CDC state for the current context. This is a required reference to an existing definiton. | |
| IncludeReprocessingIndicatorColumn | Boolean | True | 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. |
| LocaleId | Language | Inherited | This value specifies which locale is used by the dataflow task. |
| ProcessingMode | CdcProcessingMode | All | Specifies the CDC processing mode that should be used for this CDC source. Acceptable values are provided in the CdcProcessingMode enumeration. |
| Timeout | Int32 | 30 | The number of seconds before the command times out. Zero indicates an infinite time-out. The default value is 30. |
| ValidateExternalMetadata | Boolean | true | 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. |
Singleton Children
| Child | API Type | Description |
|---|---|---|
| <ErrorHandling /> | AstComponentErrorHandlingNode | Specifies the error handling defaults to apply to an entire component |
Collection Children
| Child | API Type | Description |
|---|---|---|
| <Annotations> <Annotation /> </Annotations> | AstAnnotationNode | 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. |
| <Columns> <Column /> </Columns> | AstDataflowColumnMappingNode | This is a collection of mapping nodes from source columns prior to sending them to the output path. |
| <DataflowOverrides> Multiple Choices... </DataflowOverrides> | AstDataflowOverrideNode | Provides a collection of objects to override properties of the component, its input paths, its output paths, and its consituent dataflow columns. |
