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 thing a specific GroupBy class
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 thing as a single operator to do this.
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
