One nice way to learn about hashes, arrays, scalars and references, is
to learn the perl debugger and just experiment.
There is a perl debugger tutorial in the perl documentation.

David,
I will look it up to be accurate. Give me a bit of
time.

Thanks Scott,
So %hashref now has the modified list of priorities with the task_ID as
the key.
I think I'm beginning to get the hang of this...
I do have use DBI in the code (clipped it by accident when I extracted
the segment) but you are quite right about me missing the the
fetchrow_hashref
Sorry, forgot to comment something...yeeesh
#!/usr/local/perl -wT
use strict;
use CGI;
use DBI; # need this!
my $marker = 5; # (or whatever number)
my $dbh=DBI->connect(DBI:mysql:database:localhost,"user","password");
my $sth=$dbh->prepare("SELECT task_ID, priority FROM task_list WHERE

You're not pulling in the DBI functions, for one thing. Short example of
using the hashref function built into DBI is shown below.
#!/usr/local/perl -wT
use strict;
use CGI;
use DBI; # need this!
my $marker = 5; (or whatever number)
my $dbh=DBI->connect(DBI:mysql:database:localhost,"user","passwo
Kristofer,
Thank you.
It was a big mistake to forget the method.
I think I still have problems with catching when to use $ or %. I don't
fully understand this section of the code:
my $hash = {};
while (my $rows = $response->fetchrow_hashref){
$hash->{$rows->{task_ID}} = $rows;
}

David,
You don't have a response set at execute. You have
a reference to a responce set. You need to use DBI
methods to access the results. Try this...
$response->execute();
my $hash = {};
while (my $rows = $response->fetchrow_hashref){
$hash->{$rows-
Hi all,
I have a script which mostly works, but when I get to the part with
hashes, it stops. I'm obviously doing something very basically wrong,
but I can't see what. (been staring at so long it could be anything.) A
segment of the code is below:
#!/usr/local/perl -wT
use strict;
use CGI;
# D
experimentation very easy and
interesting.
