I am trying to change the parameter name of an SQL function using an SQL command. ALTER FUNCTION seems possible but I’m unsure of the syntax. Here is the signature:

CREATE OR REPLACE FUNCTION ADVISORS_DEV.EXTERNAL_DATA_UPLOADS.ADDONE("ARG1" FLOAT)

And I’m trying to change ARG1.
https://www.ibm.com/docs/en/db2-for-zos/12?topic=statements-alter-function-compiled-sql-scalar says “The function options, parameter names, and routine body can be changed…” with ALTER FUNCTION.

Thanks
