If the operations are related and need to be "atomic", then running them individually but as a transaction is a good way to go. Turn off autocommit ($dbh{AutoCommit} => 0, and then run each statement following them with a call to $dbh->commit;. You'll need to check $@ to see if something went wrong, and if so, perform a rollback $dbh->rollback to back out all the data that did go in the transaction.

On the other hand, you can also put multiple statements in a single scalar and have DBI execute that as well, e.g. 

{
local $/;
open SQLFILE, "< file.sql" or die "Can't open file.sql: $!";
$stmts = <SQLFILE>;
close SQLFILE;
}


eval {
    # Turn off autocommit, keep from dying on erros (but print them)
    $dbh{AutoCommit} => 0; 
    $dbh{RaiseError} => 0; 
    $dbh{PrintError} => 1;
    $dbh->do($stmts);
    $dbh->commit;
};
if ($@) {
    print "Error: $@\n $DBI::errstr\n";
    $dbh->rollback;
}

Just make sure each statement ends in a ';' (semicolon).
