There is a problem with a direct mapping between database fields and hash keys if you have a multi-level hash such as a HoH.

Every record is one line of many field = value objects and these can be fairly easily mapped to and from a hash.

However, when your hash has multiple levels you need to somehow collapse your structure into one line.

With a hash of hashes as you have, this is still not too difficult: the first level ("Vlan212", "Vlan215", ...) will become the value of the key field of your record and the structure and contents of your records will be:

Key     inputQueueDrop  inputQueueFlushes  status1 lateErrors  runts
Vlan212 468723          54735              up
Vlan215 80366           80366                      3452        234

Do have a look at modules such as DBIx::Class, the so-called "Object Relational Mappers", which make using databases much easier.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
