--- Comment #5 from Nick Clemens <[email protected]> --- Created attachment 160842 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=160842&action=edit Bug 34360: Get distinct biblionumber This fixes the problem noted in the bug: [WARN] DBIx::Class::ResultSetColumn::new(): Attempting to retrieve non-unique column 'biblionumber' on a resultset containing one-to-many joins will return duplicate results. at /usr/share/koha/Koha/Objects.pm line 421 We are taking a list of items, assuming the scenario is that these are from a single biblio and possibly some host_items, then searching and ordering conditionally on whether the biblio is a serial. Current code gets the first biblio from the list - this patch adds a 'DISTINCT' to the results ebfore fetching the column To test: 1 - Find a biblio in the staff interface 2 - Transfer one of the items a few times 3 - Recreate the issue on the command line: export DBIC_TRACE=1 perl -e 'use Koha::Items; my $items = Koha::Items->search({biblionumber=>9})->search_ordered(undef,{ prefetch => ['issue','current_branchtransfers'] }); $items->next' 4 - Note warning: DBIx::Class::ResultSetColumn::new(): Attempting to retrieve non-unique column 'biblionumber' on a resultset containing one-to-many joins will return duplicate results. at /kohadevbox/koha/Koha/Objects.pm line 426 5 - Apply patch 6 - Repeat 3 7 - Error is gone -- You are receiving this mail because: You are watching all bug changes.
