Hi

i request a small help for know if it's possible.

Anyone know if they have a Sql request for
search the best value at one information:

Sample:

i have a table with:

ID int 5
Chaine int 16

and this entry:

1 12345
2 123
3 12


i am search a request in "WHERE" :

Chaine LIKE '123456789' and if he don't have into the database,
he test Chaine LIKE '12345678' etc ..
and when he arrive at 12345, he sent the ID information

thanks for your help

(PS: i use Perl for extract data)

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 =3D "9876543210"=3B
#number of rows actually returned
my $affectedrows=3D0=3B
#the offset for constructing the next global variable
my $offset=3D10=3B

#stay in this loop until we have successful result
#OR there are no rows found
while($affectedrows==0)
{
do_it()=3B
}
if($affectedrows==99) print("no rows found")=3B

sub do_it
{
# DEFINE A MySQL QUERY
$myquery =3D "SELECT * FROM $tablename where column1=3D$global"=3B
$execute =3D $connect->query($myquery)=3B
#attenuate 1 character off
$offset =3D $offset -1=3B
$global =3D substr($global=2C 0=2C $offset)=3B
#test for global having no value
if ($offset==0) $affectedrows=3D99=3B
else $affectedrows =3D $execute->affectedrows($myquery)=3B
}
