] | It looks like you can accomplish this with the [`Term::ReadKey`](http://search.cpan.org/perldoc?Term::ReadKey) module:
```
#!perl
use strict;
use warnings;
use 5.010;
use Term::ReadKey;
say "I'm starting to sleep...";
ReadMode 2;
sleep(10);
ReadMode 3;
my $key;
while( defined( $key = ReadKey(-1) ) ) {}
ReadMode 0;
... | I had the same problem and solved it by just discarding anything in STDIN after the processing like this:
```
for(my $n = 0; $n < 70000; $n++){
print $n . "\n";
}
my $foo=<STDIN>;
print "would you like to continue [y/n]: ";
chomp(my $input = <STDIN>);
print $input . "\n";

27,546,971 | Lets say, I have a table, and I want to order by field with some string and size. When I use `ORDER BY size`, it gets something like this:
```
size 100
size 105
size 110
size 115
size 85
size 90
size 95

String can be different in each row, this is just example, when there is same string - `size`. I want to retur... | 2014/12/18 | [

] | I simple way to do this is to use the length as a key:
```
order by length(size), size
```
Alternatively, use `substring_index()`:
```
order by substring_index(size, ' ', 1),
substring_index(size, ' ', -1) + 0
```
The `+ 0` does silent conversion to convert the second value to a number. | You are partially right. You could just fetch the number from your alpha numeric column
```
SELECT *
FROM MyTable
ORDER BY CAST(SUBSTRING(size, LOCATE(' ',size)+1) AS SIGNED)
