I have a problem that looks easy but i don't find a solution:
I have 2 datasets with variables like this:
Data1: A B var1 var2 var3
Data2: A B var4 var5 var6
Variables A and B have values that exist in both datasets but also values that exist in only one or another table. B is sub-classe of A.
I would like to keep only values that exist in both tables and delete the others.
I tried with merge and sql but couldn't find a solution. If anyone can help.
Thank you very much.
