Hibernate级联删除提示约束失败DELETE 语句与 REFERENCE 约束"FK_SelectCourse_StudentInfo"冲突。

数据库的关联关系如下：

StudentInfo 表snu 为主键

SelectCourse表 中 snu 参照StudentInfo 表 中snu，直接删除

Hibernate 配置文件已设置级联删除。由于Hibernate配置文件是根据Sql Server 2005 数据库反向生成修改而来的。

前台直接删除带约束关系的记录的时候，报错。错误如上图所示！

解决办法：设置Sql Server 2005 的级联删除：具体操作如图所示：

1.选择关系：打开约束。

2.找到INSERT 和UPDATE 规范：默认的更新规则 和删除规则为无操作！

3.修改更新规则和删除规则为层叠。

4.保存.

5.删除成功！
