Add Partitioning Expressions

To specify a partitioning expression, click . Use Expression Builder to create an expression.

Suppose one of the partitions is AGE. Here is a sample partitioning expression:

CASE WHEN AGE < 20 THEN 1
     WHEN AGE >=20 AND AGE < 40 THEN 2
     WHEN AGE >=40 AND AGE < 60 THEN 3
     ELSE 4
  END

Suppose this expression is named Expression_1. After you run the node, the output includes a column titled Expression_1. This column will contain the value 1 if AGE is less than 20, 2 if AGE is 20 or larger but less than 40, and so forth.
