If you regenerate the schema on stretch you get a change to SocialData I haven't committed it because I didn't kow where it came from, I don't believe it will affect anything, but wanted to document the change at the least To recreate: On debian 9 run misc/devel/update_dbix_class_files.pl (devbox or koha testing docker just do dbic) Note the change Verify all works with this change
*** Bug 22096 has been marked as a duplicate of this bug. ***
My bet would be a change in DBIx::Class::Schema::Loader, however I did not find it. social_data.isbn is a varchar and used as PK, so cannot be NULL, I guess that's why it has a default ''.
Also note that "show create table" will display the NOT NULL constraint: `isbn` varchar(30) COLLATE utf8mb4_unicode_ci NOT NULL, It looks safe to commit, and better to fix the kohastructure.sql as well.
