Re: [Monetdb-developers] How to enable functions via sql?
Stefan,
I understand how to create function from sql that receive value as input param(s). But how could i write sql function that receive array of values as input? For example i want to enable stdev function at algebra module, is it possible to do from sql?

I need to develop some extra statistical functions for MonetDB. I spent about a week to understand how to use function via sql, but still didn't have any succes results. May be someone could point me to appropriate documentation or source revision, where i could look on it?
You might be interested in these two files it shows how to add a module to SQL written in the mx language:

After that you will still have to 'create function', but that is relatively simple.
