How to MySQL search case sensitivity

(but not really)

ALTER TABLE `dimigo`.`boardpost`
MODIFY COLUMN title VARCHAR(200) CHARACTER SET euckr, COLLATE = euckr_korean_ci,
MODIFY COLUMN content VARCHAR(1000) CHARACTER SET euckr, COLLATE = euckr_korean_ci;

-- cs = case sensitive, ci = case insentive
-- ( >> theoretically << )

-- going back to euckr_bin doesn't really work in workbench
--                         ^^^^^^^
ALTER TABLE `dimigo`.`boardpost`
MODIFY COLUMN content VARCHAR(1000) CHARACTER SET euckr, COLLATE = euckr_bin;

-- or something

ALTER TABLE `dimigo`.`boardpost`
MODIFY COLUMN content VARCHAR(1000) CHARACTER SET euckr, COLLATE = utf8mb4_0900_as_cs;

end
