MergeJoin Element
The Merge Join transformation merges data from two data sets by using a join.
Attributes
  Attribute API Type Default Description
JoinType MergeJoinTransformJoinType
This value specifies what type of join to perform.

[.NET API Property: JoinType]

LocaleId Language
This value specifies which locale is used by the dataflow task.

[.NET API Property: LocaleId]

MaxBuffersPerInput Int32
This value specifies the greatest number of buffers allowed per input before blocking occurs.

[.NET API Property: MaxBuffersPerInput]

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]

TreatNullsAsEqual Boolean
This value indicates whether null values are treated as equal values.

[.NET API Property: TreatNullsAsEqual]

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]

<LeftInputPath /> AstDataflowMappedInputPathNode
This is the definition of the input path that will supply dataflow columns to the left hand side of the Merge Join operation.

[.NET API Property: LeftInputPath]

<RightInputPath /> AstDataflowMappedInputPathNode
This is the definition of the input path that will supply dataflow columns to the right hand side of the Merge Join operation.

[.NET API Property: RightInputPath]

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]

<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]

<JoinKeys>
    <JoinKey />
</JoinKeys>
AstMergeJoinKeyNode
This is a collection of key definitions that are used to determine which columns to match between the left and right inputs to determine a join match.

[.NET API Property: JoinKeys]
