Re: InstantDB: Aggregates and user-defined functions


Dirk

Thanks for pointing this out. That's definitely a bug. It'll be fixed in
3.20 beta
3 (probably several weeks away), but if it's urgent I can probably get a
patch to you a bit quicker.

Regards

Subject: InstantDB: Aggregates and user-defined functions


> Hello,
>
> I wrote user-defined function formattime. The function accepts Integer,
> Long, and Date values and returns a String. If I execute a statement

> SELECT formattime(time_col) ...
>
> the function returns the desired strings, while
>
> SELECT formattime(sum(time_col))
>
> throws a SQLException.
>
> I did some tests with the example functions that come with InstantDB and
> found that if such a function is placed around an aggregate it either
> throws an SQLException (without further information) or it returns an
> empty result set.

> Does InstantDB not allow results of aggregates to be passed to user
