select o.fullname_,p.fullname_ from fw_organization_view o left join fw_organization_view p on o.parentid_=p.id_ where o.id_=30004;
可以正常执行得到结果:当前组织全称,父组织全称
但在Hibernate中执行以上脚本
StringBuffer sql=new StringBuffer("select o.fullname_,p.fullname_ from fw_organization_view o left join fw_organization_view p on o.parentid_=p.id_ where o.id_=:id"); Query query = this.getSession().createSQLQuery(sql.toString()); query.setLong("id", id); List
得到结果
obj[0]=当前组织全称
obj[1]=当前组织全称
解决方案:把父组织全称加上别名可以得到预期的效果
将代码修改为
StringBuffer sql=new StringBuffer("select o.fullname_,p.fullname_ as parentName from fw_organization_view o left join fw_organization_view p on o.parentid_=p.id_ where o.id_=:id"); Query query = this.getSession().createSQLQuery(sql.toString()); query.setLong("id", id); List
这样得到结果为
obj[0]=当前组织全称
obj[1]=父组织全称
