我在扩展JPaRepository的界面中编写了一个删除某些对象的查询,但是当我执行查询时它抛出异常!谁能为我解释一下,并提前谢谢你:)

查询:

public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

我收到了这个错误,可以任意请,为我解释一下,谢谢大家:)

例外:

我有spring-data和hibernate配置并运行.我可以使用spring-data保存记录但由于某种原因,我无法运行将更新表中所有布尔字段的查询.

我试过这个:

@Query("update Content v set v.published = false where v.division = :division and v.section = :section")
void unPublishContent(@Param("division") String division, 
                         @Param("section") String section);

我也试过这个:

 @Query("update Content v set v.published = 0 where v.division = :division and v.section = :section")
void unPublishContent(@Param("division") String division, 
                         @Param("section") String section);

参数division和section正在实现,但表中没有变化.

ps我也在使用mysql数据库.
