https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18651 --- Comment #48 from Marcel de Rooy <m.de.rooy@rijksmuseum.nl> --- Created attachment 64455 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=64455&action=edit Bug 18651: [QA Follow-up] Fix the MAX(issue_id) calculation Found this by inserting the same issue_id in old_issues before checkin: The call to ->search( )->get_column is in scalar context and will return the number of results, i.e. always 1. If you have an issue_id 2 in old_issues, it will crash: DBIx::Class::Storage::DBI::_dbh_execute(): Duplicate entry '2' for key 'PRIMARY' The fix is fairly simple: Put get_column in list context and pick the first array entry. NOTE: Using DBIx's get_column()->max here might look simpler here. Signed-off-by: Marcel de Rooy <m.de.rooy@rijksmuseum.nl> -- You are receiving this mail because: You are watching all bug changes.
