Hi, Soufiene!

I beautified your question a bit:

Fixed the title:

extract values from global -> How to Extract Values From a Global

Fixed some bugs in English in your question.

Beautiful title and text of the question motivate DC members to answer it.

Regarding your question: you ask about extracting from a Global, but provide the result of SQL query. Do you really want to work with global? If so would you please send the screenshot or structure of the global with data?

Hi, Rubens!

Generally, Feedback group is intended for DC issues and is hidden from the main feed.

We moved feedback requests from the main feed last year cause there were so many requests that they overlapped technical discussions very much.

This year DC engine works better and there are few issues to it, so I don't mind if we can discuss some DC problems on the main feed from time to time as your post about accepting answers. If you feel that you need more focus and discussion on the particular DC problem it worth to have it on the main feed.

So it's up to you.

Hi, Sebastian! What I like about your comment that you are not saying that it is impossible.

About small COS community: how large the community should be in numbers to support the project in your opinion?

In my opinion, 3rd party library for InterSystems data platform would be supported by the community if:

1. It provides a great added value for significant part of community

2. It is easy to collaborate in development

3. It is easy to install/deinstall the library

I would add that repositories with "separate files for separate classes" and "Packages are folders" approach are much more readable if the code is exposed in UDL form. Check cacheobjectscript-udl repositories with code in UDL as examples. 

Atelier supports UDL and there are several libraries like this one which allows export Caché objectscript code in UDL easily.
