["Herman van Hovell (JIRA)" <ji...@apache.org>]

Herman van Hovell commented on SPARK-19884:
-------------------------------------------

You can use the catalog for that by calling {{spark.catalog.listFunctions().show()}}, or you can use sql and issue the {{show functions}} command.

> It would be very useful to get the list of functions that are registered with a SparkSession. Built-in and otherwise.
> This would be useful e.g. for auto-completion support in editors built around Spark SQL.
> thanks!
