签到天数: 2 天 [LV.1]初来乍到
|
结果:
一方的数据会删除,但是多方的数据不会删除,而多方的外键会被置为空(如果外键为null情况,否则报错无法删除,事物回滚)。
执行过程:
Hibernate: select qx0_.qxid as qxid1_0_, qx0_.qx as qx1_0_ from zf.dbo.TBL_QX qx0_ where qx0_.qxid=?
Hibernate: update zf.dbo.TBL_JD set qxid=null where qxid=?
Hibernate: delete from zf.dbo.TBL_QX where qxid=?
解决方法:
在manytoone.hib.xml中的配置中添加inverse=true
执行过程:(先删除多的一方的数据,再删除一方的数据)
Hibernate: select qx0_.qxid as qxid1_0_, qx0_.qx as qx1_0_ from zf.dbo.TBL_QX qx0_ where qx0_.qxid=?
Hibernate: select jds0_.qxid as qxid1_, jds0_.jdid as jdid1_, jds0_.jdid as jdid0_0_, jds0_.jd as jd0_0_, jds0_.qxid as qxid0_0_ from zf.dbo.TBL_JD jds0_ where jds0_.qxid=?
Hibernate: delete from zf.dbo.TBL_JD where jdid=?
Hibernate: delete from zf.dbo.TBL_JD where jdid=?
Hibernate: delete from zf.dbo.TBL_JD where jdid=?
Hibernate: delete from zf.dbo.TBL_JD where jdid=?
Hibernate: delete from zf.dbo.TBL_QX where qxid=?
