>                 URL: https://issues.apache.org/jira/browse/FLINK-17717
>             Project: Flink
>          Issue Type: Bug
>          Components: Table SQL / API
>    Affects Versions: 1.11.0
>            Reporter: Danny Chen
>            Priority: Major
>             Fix For: 1.11.0
>
>
> Currently, we supports syntax 
> {code:sql}
> create temporary system function catalog.db.func_name as function_class
> {code}
> But actually we dropped the catalog and db silently, the temporary system 
> function never has custom table paths, it belongs always to the system and 
> current session, so, we should limit the table path to simple identifier.
