I am connecting perl with database using DBI, I have a query.
My query is if the table.ID equal to 5, set the first one to 10, then the second one 11 and the third one 12 and so on by increasing the value of max one each time and set it to table.ID when the query is true.. till the end.
I need something like for loop, I did this code, but it does not work.
Any idea how to rewrite or fix it.
Thanks
----------------------
use strict;
use warnings;
use DBI;
my $max=10;
#connect to the databases
my $dbh=DBI->connect ('dbi:mysql:database', ' ', ' ') || die "Could
not connect to database: $DBI::errstr";
my $add_max="update table  set  table.ID=".$max."  where table.ID=5";
my $run=$dbh->prepare($add_max);
$run->execute() or die "SQL Error: $DBI::errstr\n";
while(my @row =$run->fetchrow()){
$max++;
}

Input
ID  Name
4   AAA
5   BBB
8   CCC
5   GGG
13  TTT
14  RRR
5   YYY

output should be
ID  Name
4   AAA
10  BBB
8   CCC
11  GGG
13  TTT
14  RRR
12  YYY
