Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| 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 | |
| AutoPassThrough | Boolean | True | This value specifies whether unspecified columns will automatically be passed through to the output path. The default is True. |
| LocaleId | Language | Inherited | This value specifies which locale is used by the dataflow task. |
| PivotKeyValueColumnCodePage | Int32 | 0 | This value specifies the code page of the dataflow column referenced by PivotKeyValueColumnName. |
| PivotKeyValueColumnDataType | DbType | String | This value specifies the data type of the dataflow column referenced by PivotKeyValueColumnName. |
| PivotKeyValueColumnLength | Int32 | 255 | This value specifies the length of the dataflow column referenced by PivotKeyValueColumnName. |
| PivotKeyValueColumnName | String | "PivotKeyValue" | This value specifies the name of the dataflow column that will be used for the name of the columns in the unpivoted data. The default is 'PivotKeyValue'. |
| PivotKeyValueColumnPrecision | Int32 | 0 | This value specifies the precision of the dataflow column referenced by PivotKeyValueColumnName. |
| PivotKeyValueColumnScale | Int32 | 0 | This value specifies the scale of the dataflow column referenced by PivotKeyValueColumnName. |
| PivotKeyValueColumnSsisDataTypeOverride | SsisDataType | Varigence.Utility.DataType.SsisDataType.DT_EMPTY | Specifies the SSIS Data Type that should be used for the output column. This value overrides the value specified in the PivotKeyValueColumnDataType property. |
| 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 |
| <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> | AstUnpivotColumnNode | This is a collection of column mapping definitions that control how individual columns are unpivoted. |
| <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. |
