This code divides the 150 data rows into a training data set (80%) and a testing data set (20%):

DROP TABLE IF EXISTS nb_iris_input_train;
DROP TABLE IF EXISTS nb_iris_input_test;

CREATE TABLE nb_iris_input_train AS
  SELECT * FROM nb_input_iris WHERE id%5!=0;

CREATE TABLE nb_iris_input_test AS
  SELECT * FROM nb_input_iris WHERE id%5=0;

SELECT * FROM nb_iris_input_train ORDER BY id;

SELECT * FROM nb_iris_input_test ORDER BY id;
