I wrote a class for basic Database access functionallity:
package MyDB_DB;
use DBI;
use constant DBI_STRING => 'dbi:mysqlPP:plant;merlin','uname','passwor
+d';
my $dbh;
sub DB_connect
{
$dbh = DBI->connect( DBI_STRING )
|| die "Cannot connect: $DBI::errstr\n";
#return $dbh;
}
sub DB_prepare
{
my $statement = pop;
#print 'PlantDB_DB: '.$statement."\n";
my $sth = $dbh->prepare($statement) ||
die "Cannot prepare statement: $DBI::errstr\n";
return $sth;
}
sub DB_execute
{
my $sth = pop;
$sth->execute ||
die "Cannot execute statement: $DBI::errstr\n";
}
sub DB_finish
{
$dbh->disconnect;
}
sub new
{
my $self = {};
bless $self;
return $self;
}
return 1;
in my main program i make an instance of that class and call the functions. when the program ends, i get the following message:
(in cleanup) Can't call method "close" on an undefined value at ..../mysqlPP.pm line 274 during global destruction.
maybe this is a problem related to oo-programming, maybe not. but i dont know how to deal with that message. Can you help?
