> Key: FLINK-13741
> URL: https://issues.apache.org/jira/browse/FLINK-13741
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.9.0
> Reporter: Bowen Li
> Assignee: Bowen Li
> Priority: Blocker
> Fix For: 1.9.0
>
>
> FunctionCatalog.getUserDefinedFunctions() only returns catalog functions and
> FunctionDefinitions registered in memory, but does not include Flink built-in
> functions' names.
> It means currently if users call {{tEnv.listUserDefinedFunctions()}} in Table
> API or {{show functions;}} thru SQL would not be able to see Flink's built-in
> functions.
> Should be fixed to include Flink built-in functions' names
