Hi all,
I am trying to do a user defined function written in C++ which takes the whole table as a parameter, loads it into a vector structure, and then divides the data in some groups (duplicities will occur).
How can I return the results of this grouping from the C function? Probably I’d like to store the group IDs in a separate table and create and then create an M:N table between the group IDs and the original records.
Any help appreciated.
Best regards,
