|  | ## Intersect

#### Synopsis

This operator returns these examples of an example set whose IDs are contained within another example set.

#### Description

This operator performs a set intersection on two example sets, i.e., the resulting example set contains all the examples of the first example set whose IDs appear also in the second example set. As compared to SQL, both example sets neither need to have neither the same number of columns nor the same data types. The operation does only depend on the ID columns of the example sets.

#### Input

- example set input: expects: ExampleSetMetaData: #examples: = 0; #attributes: 0
- second: expects: ExampleSet

#### Output
