Home > Predictive Query Nodes > Prediction Query > Edit Prediction Query > Add Partitioning Columns > Add Partitioning Expressions
To specify a patitioning expression, click
. Then use Expression Builder to create an expression.
Suppose that 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 that 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.
