Biml Language Reference
Pivot Element
The Pivot transformation creates a less normalized representation of a data set by taking multiple rows and converting them into a single with multiple columns.
Attributes
  Attribute API Type Default Description
LocaleId Language
This value specifies which locale is used by the dataflow task.

[.NET API Property: LocaleId]

Name String
Specifies the name of the object. This name can be used to reference this object from anywhere else in the program.

[.NET API Property: Name]

PassThroughUnmatchedPivotKeys Boolean
Causes the Pivot Transform to ignore rows containing unrecognized values in the Pivot Key column and to report the complete list of unmatched values at the end of DataFlow execution. Useful for collecting a list of values from input rows that can be used to automatically generate output columns.

[.NET API Property: PassThroughUnmatchedPivotKeys]

ValidateExternalMetadata Boolean
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.

[.NET API Property: ValidateExternalMetadata]

Singleton Children
  Child API Type Description
<ErrorHandling /> AstComponentErrorHandlingNode
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.

[.NET API Property: ErrorHandling]

<InputPath /> AstDataflowInputPathNode
This specifies the input path that will be used by this dataflow component. If an input path is not specified, the dataflow component will attempt to automatically discover an appropriate input path based on the surrounding dataflow.

[.NET API Property: InputPath]

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.

[.NET API Property: Annotations]

<Inputs>
    <Column />
</Inputs>
AstPivotInputColumnNode
This is a collection of mapping definitions that specify configuration information for each of the columns that will serve as inputs to the pivot process.

[.NET API Property: Inputs]

<Outputs>
    <Column />
</Outputs>
AstPivotOutputColumnNode
This is a collection of mapping definitions that specify configuration information for each of the columns that will serve as outputs from the pivot process.

[.NET API Property: Outputs]

<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.

[.NET API Property: DataflowOverrides]
