我得到了一个TeamPlayer对象,它的属性中包含一个Player对象。Player对象与PlayerSuspension有One-to-Many关系。
当我尝试取回所有的TeamPlayers和取回所有玩家的暂停时。它抛出以下错误。你能帮我解决问题在哪里吗?

我试图通过jpa标准api进行一个简单的联接操作,但是我得到了一个错误:

我正在尝试在JAVA中执行Hibernate查询。查询如下。
query.append(" SELECT INV.skuNum as skuNum , ITM.regDes as des, ITM.dfltWhsUom as uom, (CASE WHEN ITM.billQty IS NULL THEN 0 ELSE (CASE WHEN INV.rqstQty IS NULL THEN 0 ELSE (INV.rqstQty/ITM.billQty) END) END) AS qty, ")

你好,我正在执行一个Hive查询:

我有一个国家实体和一个公司实体,它们是一对多的关系:
@Entity
public class Country {
@OneToMany(mappedBy="country")
private List<Company> companies;
现在,我想返回一个特定国家/地区的所有公司的列表,但是当我运行以下代码时,我得到一个错误:
String queryString = "from Country as model where model.companies.id= ?";
Query queryObject = getSess
我创建了一个服务(MBean),我认为它可以正常启动/停止。正如我之前的问题所说的那样,我在结构中有我的MBean:
但是今天,我发现创建的服务在重启jboss时会出错。首先,可以将创建的服务(我的snmp代理的sar文件)放入jboss的部署路由中。我发现它真的很有效,在我的代码中,snmp代理将启动并侦听端口。但是当我重新启动jboss时,错误就出来了。如果我重启jboss,我会得到错误:
startup taking too long, not getting a response on 127.0.0.1:8081, giving up
然后我再次重启jboss,我会得到如下错误:
我有一个Person对象,它有一个training和bankAccount对象。我有以下查询
select trainings
from Person person
left join person.training trainings
left join person.bankAccount bankAccount
它可以很好地加载培训和人员,但是当我在java中查看我的培训对象时,person对象已经加载,而bankAccount对象却没有加载,hibernate使用的是代理。
我已经尝试过这个查询,但是查询出现了一个错误。
select trainings
from Person pe
有一些类似的问题,但都帮不了我。我尝试使用hybernate填充来自DB的数据,当我从单个表中提取信息时,一切都是正常的,但是当我试图对连接的表进行同样的处理时,我开始得到一个异常。这是我的一些pojo和映射文件(它们由NetBeans生成)

我的要求是检索所有图像(WAHImage)对象,无论样本(SpecimenImpl)是否为空,分类单元名称(WACensusImpl)是否为空,如果可用,按样本名称或分类单元名称排序,并首先使用null样本和null分类法来显示图像对象。
使用下面的代码,我得到了一个错误No property coalesce(wAHimage found for type WAHImage。
很明显,我的用例是,即能够查询一个实体并根据其可空子对象的属性对结果对象进行排序。这是因为QueryDSL使用交叉连接而不是左联接,而且您不能使用交叉连接按子对象属性排序。这似乎是我沮丧的根源,我现在正在寻找其他解决方
我使用的是JPA2.1、Hibernate 4.3.6Final和MySQL 5.5.37。如何编写执行连接的JPQL查询?我在下面尝试
final String jpqlQuery = "SELECT m FROM Message m LEFT JOIN MessageReadDate mr " +

" LEFT JOIN g.classroom c " +

我正在使用另一个表joins.but从一个名为PurchaseDetailContributor的表中检索记录,我遇到了查询错误。
下面是我的DAOHibernate.java类,里面写了一个方法。

我有三个表A、B和C。现在我想在HQL中执行这个sql查询:
select * from A as a
left join
B as b
on
a.id = b.id
left join
C as c
on
b.type=c.type;
需要帮助写相应的HQL。我试过这个HQL..。
Query q = session.createQuery(

LEFT JOIN
B as b
on
a.id=b.id
LEFT JOIN

我有一个包含集合的实体,我希望加载实体是懒惰的,但我得到了错误:

我正在尝试创建HQL查询,如下所示:

我正在编写一个规则查询解析器来解析一个if-然后-else块来生成一个用于获取结果集的类型化查询。下面是我准备的查询示例:

我有一个web应用程序,其中有一个搜索表单和HQL是在飞行中生成。此外,用户还可以单击列标题来根据需要对项目进行排序。有些列从非常深的结构中获取数据。
例如,我有一个HQL,它可以完美地工作:

LEFT JOIN s.product AS product
LEFT JOIN product.originCountry AS origin
WHERE s.nr = ? ORDER BY origin.name ASC
但这一次失败得很惨烈:
