RT::Handle->SimpleQuery

Hi;
rt-3.4.4, DBIx::SearchBuilder v1.33, mysql 4.18,mod_perl v2.000001;perl5
(revision 5 version 8 subversion 7) .

In using RT::Handle->SimpleQuery to update/delete is there any way it
can return to the number of records deleted/updated …
I’ll even be happy if it just return a success or failure ;
eg what I would like:
my $update = $RT::Handle->SimpleQuery("update mytable set record='rec’
where condition=‘con’);
if ($update) {
hay it works
}else{
it did n’t
}
at the moment it returns true even if ‘con’ does not exist.
Thanks;
Roy
