Java 无法提取结果集；SQL[n/a]；嵌套异常为org.hibernate.exception.sqlgrammareexception:无法提取结果集delete无法工作

嗯，我所做的只是在REST API中删除一个PAI，但出于某种原因，我得到了所有这些错误跟踪（我必须说PAI，我只知道它与Documentos和Moneda表有关，在其中一个错误中，它说我不知道，除了Remesatable之外，当它与PAI没有直接关系时）：

PaisServiceImpl:

public void getEliminaPais（长pais_id）{
布尔existpeais=paisRepo.existsById（pais_id）；
如果（existePais）{
//paisRepo.deleteById（pais_id）；
paisRepo.delete（paisRepo.findById（pais_id.get（））；//此处失败
}否则{
抛出新的IllegalArgumentException（“Pais con id”.concat（String.valueOf（existePais）.concat（“no existe”））；
}
}

Delete方法需要ID（主键）作为输入

您可以使用以下代码

paisRepo.findById(pais_id).orElseThrow(()->new YourCustomeException(Message)));

如果上述陈述没有失败。。。继续并删除该对象

paisRepo.deleteById(pais_id);

添加更多细节。实体类的实现是什么？@M.Dudek我已经用实体关系编辑了这个问题，所以最好有一个error@IlyaSazonov我用英文错误编辑了这个问题，因为在我删除一对时涉及到“remesa”的原因。不适用于我，我也有同样的错误
