Installed sqlite-3.5.4 and DBD::SQLite-1.14
I get problems with this code:
----%<--------------------------------------------
#!/usr/bin/perl -w
use strict;
use DBI;
use Data::Dumper;
use Storable;
use warnings;
sub get_session {
my ($dbh) = shift;
#$dbh->{TraceLevel} = 2;
my $sid = $ARGV[0];
my $SQL = sprintf("select a_session from sessions where id = %s",
$dbh->quote($sid));
my $sth = $dbh->prepare_cached($SQL, undef, 3);
$sth->execute;
my ($val) = $sth->fetchrow_array;
$sth->execute;
my ($val) = $sth->fetchrow_array;
#[1] my ($val2) = $sth->fetchrow_array;
#[2] $sth->finish;
my $session = Storable::thaw($val);
}
my $dbh = DBI->connect('dbi:SQLite:dbname=db/sessions.db');
print Dumper(get_session($dbh));
$dbh->disconnect;
----%<--------------------------------------------
If we run program as it looks, result will be:
DBI::db=HASH(0x87a79c)->disconnect invalidates 1 active statement
handle (either destroy statement handles or call finish on them before
disconnecting) at ./decode_sessions.pl line 26.
closing dbh with active statement handles at ./decode_sessions.pl line 26.
Note: that my database does not contain duplicated records.
If I uncomment (1), (2) or (1)+(2) result:
closing dbh with active statement handles at ./decode_sessions.pl line 26.
