http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13810 --- Comment #1 from Nicolas Legrand <nicolas.legrand@bulac.fr> --- Created attachment 36744 --> http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=36744&action=edit Change default collation to utf8_bin When upgrading database from 3.18 to master upgrade Upgrade to 3.19.00.006 (Bug 11944 - Convert DB tables to utf8_unicode_ci) may fail like this: DBD::mysql::db do failed: Duplicate entry 'ACQ-995-a' for key 'PRIMARY' at ./installer/data/mysql/updatedatabase.pl line 9671. This is from table marc_subfield_structure where the keys are made of framework (ACQ), tagfield (995) and tagsubfield (a). If we have a key ACQ-995-A it thinks the entries are duplicates, because the collation is case insensitive. It's rather annoying, since it's legit in mark to have a subfield 'a' different from subfield 'A' inside the same subfield. utf8_bin prevent updatedatabase.pl from breaking. -- You are receiving this mail because: You are watching all bug changes.
