--- Comment #2 from Keith Sorbo <keith at thesorbos.com> ---
To help those who don't use diff, I have extracted the relevant sql to the
following:

ALTER TABLE reserves DROP FOREIGN KEY reserves_ibfk_4; 
ALTER TABLE reserves MODIFY COLUMN `branchcode` VARCHAR(10) COLLATE
utf8mb4_unicode_ci NOT NULL;
ALTER TABLE reserves ADD CONSTRAINT reserves_ibfk_4 FOREIGN KEY (branchcode)
REFERENCES `branches` (`branchcode`) ON DELETE CASCADE ON UPDATE CASCADE;
