db1.public/my_store# CREATE FUNCTION_SOURCE "MySrc" WITH ( 'file' = '@/path/to/fnsrc.jar', 'description' = 'my functions' );
+-----------------+------------+------------+------------------------------------------+
|  Type           |  Name      |  Command   |  Summary                                 |
+=================+============+============+==========================================+
| function_source | MySrc      | CREATE     | function source "MySrc" was              |
|                 |            |            | successfully created                     |
