Jark Wu created FLINK-21579: ------------------------------- Summary: Support "SHOW USER FUNCTIONS" statement Key: FLINK-21579 URL: https://issues.apache.org/jira/browse/FLINK-21579 Project: Flink Issue Type: Sub-task Components: Table SQL / API, Table SQL / Client Reporter: Jark Wu
Currently, the {{SHOW FUNCTIONS}} lists all user-defined and built-in functions which is very verbose. We already introduced {{listUserDefinedFunctions()}} method on {{TableEnvironment}}. I think we can introduce a dedicate syntax to show user-defined only functions which simply calls {{listUserDefinedFunctions()}}. That would be very useful. I propose to use {{SHOW USER FUNCTIONS}} which is also supported by Snowflake [1] and Spark[2].
