Business Context
A data science team is developing a new version of a scoring algorithm. They need to load the new version ('scoringModel_v2') from the same saved table as the original ('scoringModel_v1') to run comparison tests without overwriting the original action set in the session.
Data Preparation
Define a base scoring action set named 'scoringModel_v1' and save it to a table named 'scoring_model_repo'. This table acts as a repository for the model's definition.

| 5 | { |

| 7 | definition={ |
| 8 | parms={{name='input', type='string'}}, |
| 9 | code='print("Prediction from v1 for: " || input);' |
| 10 | } |
| 11 | } |
| 12 | }; |
| 13 | RUN; |

| 15 | BUILTINS.actionSetToTable / |
| 16 | actionSet='scoringModel_v1', |
| 17 | TABLE={name='scoring_model_repo', caslib='CASUSER', replace=true}; |
| 18 | RUN; |
| 19 | QUIT; |
Étapes de réalisation
1
Load the original action set from the repository table, keeping its original name.
Copied!
| 1 | PROC CAS; |
| 2 | BUILTINS.actionSetFromTable / |
| 3 | TABLE={name='scoring_model_repo', caslib='CASUSER'}; |
| 4 | RUN; |
2
Load the exact same action set from the same repository table, but use the 'name' parameter to give it a new alias, 'scoringModel_v2', for side-by-side testing.
Copied!
| 1 | PROC CAS; |
| 2 | BUILTINS.actionSetFromTable / |
| 3 | TABLE={name='scoring_model_repo', caslib='CASUSER'}, |
| 4 | name='scoringModel_v2'; |
| 5 | RUN; |
3
Verify that both action sets, 'scoringModel_v1' and 'scoringModel_v2', now exist independently in the CAS session.
Copied!
| 1 | PROC CAS; |
| 2 | BUILTINS.actionSetInfo / actionSet='scoringModel_v1'; |
| 3 | BUILTINS.actionSetInfo / actionSet='scoringModel_v2'; |
| 4 | RUN; |
| 5 | QUIT; |
Expected Result
Two distinct action sets, 'scoringModel_v1' and 'scoringModel_v2', are present in the session, both loaded from the same source table. This confirms that the 'name' parameter successfully creates a new, aliased instance of the action set, enabling version comparison.
