问题描述
如何在休眠状态的内部查询中添加set parameter()方法?
how to add a set parameter() metheod inside the inner query in hibernate?
我已经尝试这样做,但是已经出现错误
I have try to do like this but already have a errors
这是我的代码
Query query=session.createQuery("select eq.euipmentName,eq.type from Euipment eq where eq.id in(select euipment from Quotation qt where qt. supQuotation=:ids)");
query.setParameter("ids",id);
list = (List<Euipment>)query.list();
推荐答案
我对您的查询做了一些更正: 1. qt. sup报价中有空格,我已删除 2.您子查询中的euipment没有别名,我添加qt
I've done some corrections about your query: 1. qt. supQuotation has a space, I've removed 2. euipment in you sub query haven't alias, I add qt
String hql =
"select eq.euipmentName,eq.type " +
" from Euipment eq " +
" where eq.id in (select qt.euipment from Quotation qt where qt.supQuotation = :ids)";
Query query = session.createQuery(hql);
query.setParameter("ids",id);
list = (List<Euipment>)query.list();
告诉我,如果可以的话
如果不能,请在此处发布错误,并检查您是否在类中放入了休眠映射文件
If not OK, please post here the error, and check if you have put in hibernate mappping file your classes
