This is an example that does not fully work: this is my improved Code ( Hope it will help somebody in the future) : use Data::Dump qw/dump/; use DBI; my $dbh = DBI->connect( "dbi:CSV:", "", "", { #f_schema => 'test', f_dir => '.', f_ext => '.csv', } ) or die "Could not open database: $DBI::errstr"; $dbh->{RaiseError} = 1; $dbh->{csv_tables}->{file1} = { file => 'vm.csv', }; $dbh->{csv_tables}->{file2} = { file => 'vfiler_ds.csv', }; my $query = "SELECT file1.vm_name, vm_cluster, vFiler_IP, vFiler_cluster FROM file1 join file2 WHERE file1.vm_name = file2.vm_name"; my $result = $dbh->selectall_arrayref($query); print dump($result);
