Set Minus


Synopsis

This operator returns these examples of an example set whose IDs are not contained within another example set.


Description

This operator performs a set minus on two example sets, i.e. the resulting example set contains all the examples of the minuend example set whose IDs do not appear in the subtrahend example set. Please note, that the subtrahend example set must be the first on the ioobject stack, i.e. it must be the last example set which has been added. As compared to SQL, both example sets need 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.
