Should I not use the new stack, or in the future we create a new issue to refactor all built-in functions to the new stack? Like this PR [https://github.com/apache/flink/pull/19988] . If I use the new stack, I will delete the `StringCallGen#generateAscii` and add an `AsciiFunction` like IfNullFunction in https://issues.apache.org/jira/browse/FLINK-20522 IMO, if we change `StringCallGen#generateAscii`, we can create a new issue. was (Author: ana4): [~twalthr] I only support existing built-in functions no more new functions in this issue.

See > https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/functions/systemfunctions/ > for more details. There are two columns for each built-in function: *SQL > Function* and *Table Function*, if a function is not supported in *Table > API*, the *Table Function* column is documented as *N/A*. We need to evaluate > each of these functions to ensure that they could be used in both SQL and > Table API. -- This message was sent by Atlassian Jira (v8.20.7#820007)
