Association Rule : Settings in PL/SQL

Question

I've developed a model in ODM GUI for association rules.
I'm now looking to develop the same in PL/SQL.
I need to know how to specify the case id that has 2 attributes (CUST_ID and TIME_ID) and I have the PROD_ID as the ITEM ID. I have the following settings table and PLSQL
BEGIN
INSERT INTO assoc_sample_settings (setting_name, setting_value) VALUES
(dbms_data_mining.algo_name, dbms_data_mining.ALGO_APRIORI_ASSOCIATION_RULES);
INSERT into assoc_sample_settings (setting_name, setting_value) VALUES
(dbms_data_mining.prep_auto, dbms_data_mining.prep_auto_on);
INSERT into assoc_sample_settings (setting_name, setting_value) VALUES
(ODMS_ITEM_ID_COLUMN_NAME, ‘PROD_ID’);
END;
DBMS_DATA_MINING.CREATE_MODEL(
model_name => 'ASSOC_MODEL_2',
mining_function => dbms_data_mining.association,
data_table_name => 'SH.SALES',
case_id_column_name => ‘CUST_ID, TIME_ID’,
target_column_name => null,
settings_table_name => 'assoc_sample_settings');
Is this correct? for setting the CASE ID to 'CUST_ID, TIME_ID', is this correct and/or in the correct place
Also the setting of the PROD_ID also correct?
Do I need to use the ODMS_ITEM_VALUE_COLUMN_NAME setting ?

Answer 1

Thank you for your reply, but it is still not working. There is the code that I have used for setting up and running. What is missing or incorrect with the following. The data is from the SH.SALES table.
Settings Table
BEGIN
INSERT INTO assoc_sample_settings (setting_name, setting_value) VALUES
(dbms_data_mining.algo_name, dbms_data_mining.ALGO_APRIORI_ASSOCIATION_RULES);
INSERT into assoc_sample_settings (setting_name, setting_value) VALUES
(dbms_data_mining.prep_auto, dbms_data_mining.prep_auto_off);
INSERT into assoc_sample_settings (setting_name, setting_value) VALUES
(dbms_data_mining.ODMS_ITEM_ID_COLUMN_NAME, ‘PROD_ID’);
COMMIT;
END;
Create the view
CREATE VIEW ASSOC_DATA_V AS (
SELECT RANK() OVER (ORDER BY CUST_ID, TIME_ID) CASE_ID, t.*
FROM SH.SALES t );
Create the model
BEGIN
DBMS_DATA_MINING.CREATE_MODEL(
model_name => 'ASSOC_MODEL_2',
mining_function => DBMS_DATA_MINING.ASSOCIATION,
data_table_name => 'ASSOC_DATA_V',
case_id_column_name => ‘CASE_ID’,
target_column_name => null,
settings_table_name => 'assoc_sample_settings');
END;
BEGIN

ORA-40104: invalid training data for model build

Any ideas what is causing this?
