Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| ConnectionName | AstOleDbConnectionNode | This value specifies a direct reference to the OLE DB connection where the query will be executed. 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 | |
| DefaultCodePage | Int32 | 0 | This value specifies which default code page to use when the data source does not specify a default code page. |
| EnableInferredMember | Boolean | True | This value determines whether the Slowly Changing Dimension transformation will check for inferred member records that require updating. |
| FailOnFixedAttributeChange | Boolean | True | This value indicates whether the transformation fails when changes occur in row columns with Fixed attributes. The default value is False. |
| FailOnLookupFailure | Boolean | False | The value determines whether the transformation fails if no match for an incoming row is found in the lookup table. The default value is False. |
| IncomingRowChangeType | SlowlyChangingDimensionIncomingRowChangeType | Detect | This value determines whether incoming rows are handled as new rows, or whether the type of change is detected for each column and the incoming rows directed to output based on types of changes they contain. |
| InferredMemberIndicator | String | This value specifies the name of the column which is used to store inferred member records. | |
| LocaleId | Language | Inherited | This value specifies which locale is used by the dataflow task. |
| UpdateChangingAttributeHistory | Boolean | False | This value specifies whether or not historical attribute changes sent to the output path for changing attribute updates. |
| 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 |
|---|---|---|
| <Query /> | AstDirectResourceNode | The AstDirectResourceNode type provides the facility to directly input text data for use in the referencing Biml object. This is a required property |
| <CurrentRowWhere /> | String | String is the .NET Framework String class. More information can be found at http://msdn.microsoft.com/en-us/library/system.string.aspx. |
| <ErrorHandling /> | AstComponentErrorHandlingNode | Specifies the error handling defaults to apply to an entire component |
| <InputPath /> | AstDataflowInputPathNode | AstDataflowInputPathNode is used to model input paths in a SQL Server Integration Services dataflow task. Connections are made by referencing an appropriate output path. |
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> | AstScdTypeColumnMappingNode | This is a collection of column mapping definitions that determine how each of the specified columns will be handled with respect to value changes. |
| <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. |
