Derby数据库和idea的问题

Question

我用Derby数据库在idea中写了一个能够做到对英语单词进行增删查改的单词簿，然后我运行之后呢它出现这个错误，我不知道该怎么改Caused by: ERROR 23505: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'SQL231207161913090' defined on 'WORD_TABLE'.请大家赐教

看报错原因，是你往数据库插入数据的时候主键重复了。
