ORA-02449 的问题

ORA-02449:unique/primary keys in table referenced by foreign keys.由于唯一/主键被其他外键引用

可以1.禁用该约束

查找该约束: select * from user_constraints c where c.table_name='TABLE_NAME';

该条记录

alter tableTABLE_NAME disable constraintCONSTRAINT_NAME CASCADE;

2.删除表的时候，级联删除约束

drop table TABLE_NAME cascade constraints;
