now my code is running but output is not correct I am getting 'q' for all label in first row of table (TK) and '1' for all label in the second row of the same table

Yes, I ran it and got the same results as you. I (mistakenly) thought that my $row = $sh2->fetchrow_arrayref provided a fresh instance of $row to push onto the @name array. I confess I'm not really sure what is happening or why. It seems that all entries in the array are the last entry. Perhaps someone else could explain this better.

To get the correct info, I made the change below.

#!/usr/bin/perl
use strict;
use warnings;
use DBI;

my $dbh = DBI->connect("dbi:SQLite:dbname=users.lite","","",
    or die "Can't connect";
    
my $sh2=$dbh->prepare("select code,name from level ");
$sh2->execute() or die();
my @name;

while (my @row = $sh2->fetchrow_array) 
{
    push @name, [@row]; 
} 

$dbh->disconnect or die $!;

for my $i ( 0 .. $#name) {
    print "code: $name[$i][0] name: $name[$i][1]\n";    
}

__END__
*** the program prints
code: 001 name: Level1
code: 002 name: Level2
code: 003 name: Level3
code: 004 name: Level4
code: 005 name: Level5
code: 006 name: Level6
code: 007 name: Level7
code: 008 name: Level8
code: 009 name: Level9
