I have a hash called tab2hash that has
tablenames as key and hashnames as value. I want to
initialize the hashes with the values from DB tables. And I
have the code below, however when i print the hashes
they are empty. This line is where the hash is being populated
$$VALUE_1{$k1} = $v1;
Please help with your suggestions.
my %tab2hash = qw(divisions divH regions regH);
sub initHashesArraysFromDB
{
my ($k1, $v1);
while ((my $KEY_1, my $VALUE_1) = each %tab2hash)
{
my $sth = $dbh->prepare("select * from $KEY_1");
$sth->execute || die "Cannot execute query: " .DBI->errstr;
while (my @row = $sth->fetchrow())
{
my $f1 = 0;
foreach my $col (@row)
{
if($f1 == 0)
{
$f1 = 1;
$k1 = $col;
$v1 = $col;
}
else
{
$v1 .= "|" . $col;
}
}
$$VALUE_1{$k1} = $v1;
}
}
}
