I've searched and read all over but can't figure this out.
I have this "$hash_ref" that comes from a DB query using "$dbh->selectall_hashref" in the DBI.
As seen from Data::Dumper this is my data:
$VAR1 = { '1' => { 'PointType' => 'Camera', 'idType' => '1' }, '2' =>
+{ 'PointType' => 'School', 'idType' => '2' } };
If I want to just get the "PointType" by knowing the "idType" how would I do that?
I've guessed $hash_ref{'1'} or $hash_ref->{'1'} hoping to get "Camera" back but it doesn't work.
How do I do this, I'm lost?
