[Koha-devel] Catalogue Statistics report - limiting by dewey number

Greetings all!
Got a bit of a question here. As part of our academic (re)accreditation
process, we need to provide a list of books aquired in a specific
subject area over the past year. Fantastic - the Catalogue Report should
do all that. (Well, it should do it when the patches in bug report 10608
are applied!)
My problem: how to restrict the report according to the dewey number of
the items. (This is, I think, the easiest way for us to show which books
relevant to a specific subject area). However, looking at the code, it
appears in catalogue_stats.pl that $has_dewey is disabled (in fact, the
comment says it doesn't work - not sure why it and its remnants remain
in both the perl and the templates???)
So, unable to filter on dewey number, I've taken to filtering on the
koha full call number. The problem is that I want to filter on the dewey
part of the call number - not the full string. And this causes problems.
Let me demonstrate. Using the current code path, if I'm searching for
items between 227.0 and 227.15, I get 299 records (see APPENDIX A).
Changing the code to cast the call number to a float as below (which
gives me just the dewey localtion)
if (@$filters[4]){
@$filters[4]=~ s/\*/%/g ;
$strcalc .= " AND items.itemcallnumber >= (0+" .
$dbh->quote(@$filters[4]) .")";
}
if (@$filters[5]){
@$filters[5]=~ s/\*/%/g;
$strcalc .= " AND items.itemcallnumber <= (0+" .
$dbh->quote(@$filters[5]) .")";
}
now gives me 308 records (see APPENDIX B) - including ones like 227 BRU
where the decimal component (227.0) is implied.
My question (at last!): is changing the code as above the right way to
go about fixing this problem? (I realise that ideally one would want to
make it an option in the report....).
This same issue applies to other report modules - such as the
circulation stats....
Any suggestions? How do other libraries deal with this?
God bless,
