Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| ConnectionName | AstOleDbConnectionNode | This value specifies the connection to an instance of SQL Server to use when creating temporary SQL Server tables required by the Fuzzy Grouping transformation algorithm. 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 | |
| Delimiters | String | ",.;:-\"'&/\\@!?()<>[]{}|#*^%\t\r\n " | This value specifies which white-space and punctuation characters are used to separate strings into multiple words. |
| Exhaustive | Boolean | False | This value specifies whether every input record is directly compared against every other input record. The default value is False. If set to True, performance will be extremely slow unless the number of input records is very small. This option is primarily intended for debugging purposes and should be used with care. |
| InputKeyColumnName | String | "_key_in" | This is the name of the dataflow output column that will contain the input key value. |
| LocaleId | Language | Inherited | This value specifies which locale is used by the dataflow task. |
| MaxMemoryUsage | Int32 | 0 | This value specifies which white-space and punctuation characters are used to separate strings into multiple words. |
| MinSimilarity | Int32 | 80 | This value specifies the minimum similarity threshold, expressed as a value between 0 and 100. The default value is 80. |
| OutputKeyColumnName | String | "_key_out" | This is the name of the dataflow output column that will contain the output key value. |
| SimilarityScoreColumnName | String | "_score" | This is the name of the dataflow output column that will contain the similarity score value. |
| 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 |
|---|---|---|
| <Columns> <Column /> </Columns> | AstFuzzyGroupingColumnMappingNode | This is a collection of mapping definitions with configuration for each column. This is a required property |
| <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. |
| <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. |
