Hi there,

I'm a bit struggling with the syntax for filter function, after it changed from Oct2014 to Jul2015.

I have looked at the release notes, but they don't seem to even mention this change of syntax.

This used to work in Oct2014:

create filter function maxlevenshtein(s1 string, s2 string, k int) 

external name str."distjoin_levenshtein";

select t.name, f.name 

from sys.tables t, sys.functions f

where t.name maxlevenshtein(2) f.name;

In Jul2015, if I look at Niels' comment in https://www.monetdb.org/bugzilla/show_bug.cgi?id=3702 , it should be something similar to

select t.name, f.name 

from sys.tables t, sys.functions f

where [t.name] maxlevenshtein [f.name, 2];

But this is still not right. How should it be? And should I change the SQL / MAL / C interface of the function as well?

Thanks,
