我想用这种方法从 2 个 sql 表中选择一个结果:
@Override
public List<Object> getAll() {
Query query = entityManager
.createQuery("select a.idAccount, c.firstName, c.lastName, a.dateOfCreation, a.bonusPoint from account a ,customer c where c.identity=a.id_Customer and a.bonusPoint>=5000 and TO_DAYS(NOW()) - TO_DAYS(a.dateOfCreation) >=60");
return query.getResultList();
}
我想在数据表中显示这个查询,所以我在 ManagedBean 中使用数据模型:
public DataModel getDataModel() {
dataModel.setWrappedData(gIftManagementRemote.getAll());
return dataModel;
}
在 jsf 页面中,我使用了一个数据表,但我不知道应该在“var”中输入什么:
<rich:dataTable rows="15" id="table" value="#{assignGiftManagement.dataModel}"
**var**="?????">
所以当我运行这个页面时,我有这个例外:
javax.servlet.ServletException: java.lang.IllegalArgumentException: org.hibernate.QueryException: could not resolve property: id_Customer of: tn.esprit.bankSprint2.persistence.Account [select a.idAccount, c.firstName, c.lastName, a.dateOfCreation, a.bonusPoint from tn.esprit.bankSprint2.persistence.Account a ,tn.esprit.bankSprint2.persistence.Customer c where c.identity=a.id_Customer and a.bonusPoint>=5000 and TO_DAYS(NOW()) - TO_DAYS(a.dateOfCreation) >=60]
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
我应该做什么?!
