数据被引用，不能删除。

Could not execute JDBC batch update; SQL [update bbs_member_magic set uid=null where uid=?]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

先要删除相关的数据

难道手工在数据库删除？

是的，要把相关联数据清除

每次登录bbs.jeecms.com都报500

手动上数据库删除也会报错，也是约束！外键约束！头大！

会员级别是和很多数据有关联，最好不要删除
