Implementation Reference
- The handler function that implements the core logic of the 'sec_userDbPermissions' tool. It queries the DBC.AllRightsV view to retrieve database, table, and column permissions for the specified user.def handle_sec_userDbPermissions(conn: TeradataConnection, user_name: str, *args, **kwargs): """ Get permissions for a user.
