If you want to map an array into a hash, replace 
    %hash_table = (@PARTS);

with 
    %hash_table = map { $_ => 1 } @PARTS;

[download]

What your code does is to use odd entries as the hash key and even entries as the value of that key. The alternative says each entry is a hash-key, having a (trivial) value of 1.

One suggestion: move the code that opens/loads <PARTS> before the loop through your database.

Good luck!
