you'll need to write a recursive routine to call the same sql statement
and iterate from the largest value and attenuate that value by 1 each time
# file: test.pl been a few years but this should work
#initialize your variable that you will attenuate
my $global = "9876543210";
#number of rows actually returned
my $affectedrows=0;
#the offset for constructing the next global variable
my $offset=10;
#stay in this loop until we have successful result
#OR there are no rows found
while($affectedrows==0)
{
do_it();
}
if($affectedrows==99) print("no rows found");
sub do_it
{
# DEFINE A MySQL QUERY
$myquery = "SELECT * FROM $tablename where column1=$global";
$execute = $connect->query($myquery);
#attenuate 1 character off
$offset = $offset -1;
$global = substr($global, 0, $offset);
#test for global having no value
if ($offset==0) $affectedrows=99;
else $affectedrows = $execute->affectedrows($myquery);
}
