I want to use information from my Gforum tables in a global for my Links pages.

One database holds both the Gforum and Links tables.
The Gforum table prefix is gforum_
The Links table prefix is links_

For example, if I want a global that contains the subject of post #100,
in Gforum the global is:

sub {
my $tempsubject = $DB->table('Post')->select(['post_subject'], { post_id => 100 })->fetchrow;
return $tempsubject;
};

What is the same global in Links?

Thank you!!
