Hello

Hello,

I am a student at a university in France.

I work on MonetDB, Windows platform. A pity,because all serious development is done on Linux platforms.

I have some questions:

I want to optimize the "Group by" function of the SQL module in order to create a new function combining the "Group by" function and another function. For this I want to know:

1 - How to locate the class containing the code of the "Group by" function MonetDB is not an object-oriented program, so there is no such

...

2 - How to edit the code in question to change it First look at the code produced by: explain select * from tables group by name,query; and you will understand that there is no such

...

3 - Which editor should be used to compile the project. vi ;)

A more helpful reply: look at buildtools/doc/windowsbuild.rst which is part of the source tree. Building on Windows is not for the faint of heart. You need to do a lot of preparatory work in order to get a usable environment.

...

4 - I tried to use "Visual Studio 2012" to open the project "MonetDB" but I have not managed to do. see above

regards, Martin
