I try to write a script that gathers some information about tables using Perl and the DBI module.
I have already all information regarding the columns but I can't find a way to determine which column is the primary key.
I tried googling for it but somehow the only "solution" I found did not wor (http://www.perlmonks.org/?node_id=343462)
Does anybody know how to do it? That would be very helpful
Edit: I am querying an oracle database version 12.
