Hi, sorry, two hash related questions in one day .. but this has got me a bit stuck.
I have a mysql database table that kind of looks like this, the table is called "view1" and a snippet of that table (SELECT'ing just rows with serial number 0629AN1200) is below
i am creating a hash of hashes from this data ,using the code below
when i run this script I get this output...note that even though I have asked fetchall_hashref to create keys based on 'nic_name', the output below still ALSO has 'nic_name' as a key value pair of the sub hash ..... ?
Is there something im doing wrong here ? I was under the impression that the line ...
would set the top level keys of the hash of hashes. .(which it seems to have successfuilly done) ... but would then have the intelligence to omit that particular key/value pair from the sub hash?
am i missing something here??
Any help would be great

This is driving me mad, where am I going wrong?
The relevant segment of code:
sub getndsybcons {
my @servers=@{$_};
my @sybservers=@{$_};
my %results;
foreach my $server(@servers) {
my $biggestsyb;
my $biggestsybval=0;

I have a script with dynamic hash of hashes , and I want to print the entire hash (with all other hashes).
Itried to do it recursively by checking if the current key is a hash and if yes call the current function again with refference to the sub hash.
Most of the printing seems to be OK but in... (1 Reply)

SELECT nic_name,nic_duplex,nic_speed,nic_ip FROM network_table WHERE hostname = "server1"
result is this (ive delimited with a pipe for ease of reading)

Hi there
I have a hash of hashes made up of the following data

bge2|1000|full|10.36.100.23
which when i turn into a hash, would look like this inside the system
bge0 ->
nic_speed -> 100
nic_duplex -> half

Hi,
Is there any quick way to use pull out keys that match a specific regex pattern?
eg
%hash ;
$hash(123,456) = xxx;
$hash(123,457) = xxx;
$hash(123,458) = xxx;
$hash(223,459) = xxx;
I need a fast way to get all the keys that start with 123..
Meaning I should get

Hello experts. I'm having problems with a snippet of code.
I was hoping to get help/advice to correct.
A file that this script parses has changed to the point where
I can no longer use a scalar, it looks as though I need to
create an array for a hash of hashes below.
The first output of... (1 Reply)
