The Class::DBI docs include the following suggestion for wrapping txns:

sub do_transaction {
                my $class = shift;
                my ( $code ) = @_;
                # Turn off AutoCommit for this scope.
                # A commit will occur at the exit of this block automa
+tically,
                # when the local AutoCommit goes out of scope.
                local $class->db_Main->{ AutoCommit };
                # Execute the required code inside the transaction.
                eval { $code->() };
                if ( $@ ) {
                        my $commit_error = $@;
                        eval { $class->dbi_rollback }; # might also di
+e!
                        die $commit_error;
                }
        }

Can some explain this line

                local $class->db_Main->{ AutoCommit };
[download]

Is this a set statement? The DBI docs mention setting

$dbh->{AutoCommit} = 0
[download]

to turn on txns, but clearly the local statement in the routine above doesn't have the =0. What is this  local statement doing?

Thanks
