我试图在OneToMany关系中根据子类的ID属性简单地过滤掉结果,但是Hibernate(4.1.9.Final)正在生成一个Left Outer Join而不是一个内连接,从而返回结果我不想要。
型号:
父:
@Entity
@Table(name = "CATEGORY")
public class Category
{
@Id
@Column(name = "CATEGORYID")
private int ID;
@Column(name = "CATEGORYNAME")
private String name;
@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "CATEGORYID")
@Filter(name = "TEST_RUN_ID_FILTER")
private Collection<TestCase> testCases
...
}
子:
@Entity
@Table(name = "TESTCASE_NEW")
@FilterDef(name = "TEST_RUN_ID_FILTER", defaultCondition = "TESTRUNID in (:IDS)", parameters = { @ParamDef(name = "IDS", type = "int") })
public class TestCase
{
@Id
@Column(name = "TESTCASEID")
private int ID;
@Column(name = "TESTCASENAME")
private String name;
@Column(name = "STATUS")
private String status;
@Column(name = "TESTRUNID")
private int testRunId;
...
}
DAO:
public List<Category> getAllCategoriesForTestRuns(List<Integer> testRunIDs)
{
Session session = getSession();
session.enableFilter("TEST_RUN_ID_FILTER")
.setParameterList("IDS", testRunIDs);
Query query = session.createQuery("FROM " + Category.class.getSimpleName());
List<Category> result = query.list();
return resul2t;
}
如何告诉Hibernate使用内连接?
答案 0 :(得分:0)
您可以尝试以下内容:
select c from Category c inner join c.testCases tc
