Hi yinhua, As Chesnay suggest, document is a good way. You can find descriptions and example for each udf. If you only want to get a list of name, you can also take a look at the flink code(i.e., the BasicOperatorTable.builtInSqlOperators <https://github.com/apache/flink/blob/master/flink-libraries/flink-table/src/main/scala/org/apache/flink/table/validate/FunctionCatalog.scala#L321> ).
Hope this helps.
