Re: Re: Creating a hash of arrays from row data

I just want to say: Thanks to all, I found all posts interesting. My program immediately started to work. And I know a lot more about references. One more slightly off topic question: Is there also a mailing list for 'intermediate' perl programmers. I subscribed to [EMAIL PROTECTED] but have ye

Creating a hash of arrays from row data

Hi all, I could use some help with the following problem: I have rows of data (coming in from DBI) looking like this: Key1, Key2, Date_from, Date_to, Value 1, 1, 01-10-2002, 31-10-2002, value1 1, 1, 01-11-2002, 30-11-2002, value2 1, 2, 01-10-2002, 31-10-2002, value3 1, 2, 01-10-2002, 30-10-2002
