Horia Mocioi commented on CASSANDRA-14126:
------------------------------------------
Hello,
I have tested the patch and it works fine. I also reviewed the code and it
looks fine to me.
I also tried to change a little bit the javascript function so I can use the
"input" parameter. Unfortunately, the js code cannot evaluate the variable
since it's not defined.
{quote}CREATE OR REPLACE FUNCTION first_int(myInput int) RETURNS NULL ON NULL
INPUT RETURNS int LANGUAGE javascript AS '(function(myI)\{return
myI;})(myInput);';
{quote}
And the error:
{quote}Traceback (most recent call last):

line 1044, in perform_simple_statement

message="execution of 'testkeyspace.first_int[int]' failed:

"myInput" is not defined in <eval> at line number 1"
{quote}
Is there any other way to pass in the argument or am I passing it in a wrong
way?
