Hi everybody,

I have a sqlite database compressed with bzip2. I need to do some query into database without unzip into a file but using only a memory buffer. I tried with this code but didn't work and I didn't understand why. 
use DBD::mysql;
use Time::Local;
use strict ;
use warnings ;
use IO::Uncompress::Bunzip2 qw(bunzip2 $Bunzip2Error) ;
use IO::File ;

my $input = shift;
my $buffer ;
bunzip2 $input => \$buffer, BinModeOut => 1 or die "bunzip2 failed: $B
+unzip2Error\n";
opendb(\$buffer);
exit;

sub opendb
{
    my $file = shift;
    
    my $dbsql = DBI->connect("dbi:SQLite:${file}", "", "",    {RaiseEr
+ror => 1, AutoCommit => 1});

    my $sq_1;
    my $sh_1;

    $sq_1 = "select * from tbl_xxx";
    
    $sh_1 = $dbsql->prepare($sq_1);
    $sh_1->execute();
    
    while( my $field = $sh_1->fetchrow_hashref()) {
        print "$field->{'pos'},";
    }
    print "\n";
}
