Need help from SQL Developer users

Question

I’d like to run Decision Tree models in SQL Developer for monthly predications after running in ODM manually.
I created PL/SQL Packages under Tools from ODM, and compiled them in SQL Developer successfully. According to Oracle documents, I should be able to run the same DT models (using create or replace PACKAGE BODY "DATAMININGACTIVITY1" .......). However, I am unable to run the entire “Package Body” or any part of it. One of the error messages shows "The select program is in an invalid state for running". I also tried to use "Call" to call functions to run my SQL Package, but that didn't work either. So far, the only SQL works for me is to create a view from a table.
Please share how you use SQL to run models. Thanks, DC

Answer 1

In PL/SQL Block you will see something like below.
In the most simple case you need to supply to arguments ( see bold )
CASE_TABLE := *'YOUR_TABLE_NAME_FOR_MODEL_BUILD'*;
MODEL_NAME := *'MODEL_NAME_FOR_YOUR_NEW_MODEL';*
That would be enough to build a model.
Thanks,
Jim
