Hello monks, I'm totally new to Perl (just 2 days coding!), and so far I'm liking it. I've been assigned a task in Perl, that basically is this:

• I should script a loader, that will read a .tsv with 3 columns
• This records should be loaded into a database, which will have the same columns that the .tsv plus a 'Timestamp' one
• There are several conditions to operate in the database; # If there already exists record in DB with given ID, that record is updated with information from file and Update_timestamp is set to system current timestamp. # If new record is detected in file, new record is created in DB with attributes from file # and Update_timestamp is set to system current timestamp. # If any update is detected, record in DB is updated and Update_timestamp is set to system current timestamp. # If record does not exist in the file, no action is taken.

my biggest concern is that I don't know which will be the best way to "compare" records from the file and the DB to properly update the DB. For now, I have used Text::CSV for reading the file and converting it to a hash ref array, but I'm not sure what will be the best solution for comparing this data with the DB (I'm using MySQL)... I've tried 'selectall_hashref' from DBI class and the result is messed... Dear wise monks, what would be your approach
