Get duplicate data from coll.
Mar 18 2023 | 8:18 pm
Hi! I know this is the kind of topic that a lot of posts in this forum answers, but I can't get the exact information i'm looking for.
I have three colls (could be more) in which I have symbols. Ex : Coll 1 : 1, apple; 2, orange; 3, mango; 4, mulberry;
Coll 2 : 1, watermelon; 2, orange; 3, avocado; 4, apple;
Coll 3 : 1, orange; 2, strawberry; 3, papaya; 4, apple;
As you can see, "apple" and "orange" are in each of the colls. I'd like to populate a new coll with only these two symbols.
Coll final : 1, apple; 2, orange;
I know there are some posts about removing the duplicates, but not so much about keeping the duplicates, and it's often about numbers, maybe I could do something with converting the symbols to ascii and itoa back when the duplicates are filtered but i can't seem to find the exact way of doing this... Thanks in advance for your help!
