LISTAGG implementation is missing

[akond]

H2 has several aggregating functions, such as LISTAGG

LISTAGG ( [ DISTINCT|ALL ] string [, separatorString]
[ ON OVERFLOW { ERROR | TRUNCATE [ filterString ] { WITH | WITHOUT } COUNT } ] )
withinGroupSpecification
[FILTER (WHERE expression)] [OVER windowNameOrSpecification]

Are there any plans to implement those?

[source-c]

We actually implemented only those basic features we currently use. However, if something is needed it is a good reason to take a look at, so thank you for the request. Perhaps you have some testcases for that functionality?

I've written a small implementation of the LISTAGG ... WITHIN GROUP (...) case. I admit I am not an expert on honey.sql, so the implementation may seem too trivial, clumsy even; however, it works for me.

Ok. Will take a look at all of that. Thank you anyway!
