Changing model ownership

As a superuser or model owner, you can reassign model ownership with ALTER MODEL as follows:

ALTER MODEL model-name OWNER TO owner-name

Changing model ownership is useful when a model owner leaves or changes responsibilities. Because you can change the owner, the models do not need to be rewritten.

Example

The following example shows how you can use ALTER_MODEL to change the model owner:

1. Find the model you want to alter. As the dbadmin, you own the model.

   => SELECT * FROM V_CATALOG.MODELS WHERE model_name='mykmeansmodel';
   -[ RECORD 1 ]--+------------------------------------------
   model_id       | 45035996273816618
   model_name     | mykmeansmodel
   schema_id      | 45035996273704978
   schema_name    | public
   owner_id       | 45035996273704962
   owner_name     | dbadmin
   category       | VERTICA_MODELS
   model_type     | kmeans
   is_complete    | t
   create_time    | 2017-03-02 11:16:04.990626-05
   size           | 964
   

2. Change the model owner from dbadmin to user1.

   => ALTER MODEL mykmeansmodel OWNER TO user1;
        ALTER MODEL
   

3. Review V_CATALOG.MODELS to verify that the owner was changed.

   => SELECT * FROM V_CATALOG.MODELS WHERE model_name='mykmeansmodel';
   
   -[ RECORD 1 ]--+------------------------------------------
   model_id       | 45035996273816618
   model_name     | mykmeansmodel
   schema_id      | 45035996273704978
   schema_name    | public
   owner_id       | 45035996273704962
   owner_name     | user1
   category       | VERTICA_MODELS
   model_type     | kmeans
   is_complete    | t
   create_time    | 2017-03-02 11:16:04.990626-05
   size           | 964
