文档解释
ORA-25158: Cannot specify RELY for foreign key if the associated primary key is NORELY

Action: Change the option of the primary key also to RELY.
。
ORA-25158 错误指示不能为具有NORELY主键的外键指定RELY选项。
官方解释
如果创建外键时主键属性为NORELY,则不能为外键设置RELY属性。所以要么让外键使用NORELY属性,要么让主键使用RELY属性。
常见案例
当您使用以下语句创建外键时,将会出现这个错误:
ALTER TABLE child
ADD CONSTRAINT child_fk
FOREIGN KEY (parent_id)
REFERENCES parent (id);
一般处理方法及步骤
要解决这个错误,您可以为主键添加RELY属性:
ALTER TABLE parent
MODIFY id NOT NULL RELY;
或者您可以为外键添加NORELY属性:
ALTER TABLE child
ADD CONSTRAINT child_fk
FOREIGN KEY (parent_id)
REFERENCES parent (id)
NO RELY;
