Using the Distinct Operator Property Editor
See Also
The Distinct operator retains records input from a relation that are unique. If duplicate records exist, they will not be sent out from the Distinct operator. All attributes of records must match to be filtered with the Distinct operators.
You typically use the Distinct operator in conjunction with a relation output from another operator. The Distinct operator does not forward duplicate records from input to it. Typical operators whose input the Distinct operator uses include:
- Partitioned Window operator
- Tuple-Based Window operator
- Attribute-Based Window operator
- Time Based Window operator
- Relation Map operator
- Relation Aggregator operator
To create a Distinct operator:
- Drag a Distinct operator from the Palette to the Design view.
- Connect an input from an operator that has a relation result.
- Click the Distinct operator icon. The property editor opens with the name of the Distinct operator and the output schema name populated. The property editor displays the schema of the data that is input to the Distinct operator.
- Click Ok.
