hi pDale
this is the entire code ...
============
while(my $row_href = $sth->fetchrow_hashref)
{
print "$row_href->{'area'}\n";
}
foreach my $key (keys %$row_href)
{
print "hi\n";
print "$key = ".$row_href->{$key}."\n";
}
=================
the "while" correctly outputs the values for the column/field "area" - so
the hash at that point has the data.
the "foreach" outputs nothing - does not even enter the loop since the
"hi" does not print....
hope you can help!
