from子句中的JPA/hibernate子查询

我们使用JPA和hibernate作为提供程序， 我们有一个查询，该查询在FROM子句中包含一个带有子查询的联接，但出现以下错误：

org.hibernate.hql.ast.QuerySyntaxException:意外标记：近 第1行第75列[从中选择sd com.hp.amber.datamodel.entities.analysis.SnapshotDates sd，选择 maxx.changeDate maxChangeDate，x.viewId，x.state FROM com.hp.amber.datamodel.entities.analysis.SnapshotDates x其中

---

x、 changeDate我不认为HQL可以在from子句中执行子查询

注意这句话：

请注意，HQL子查询只能出现在select或where子句中

我想您可以将其更改为本机查询并以这种方式执行。

您的SQL是：

从快照日期sd中选择sd， 选择maxx.changeDate maxChangeDate、x.viewId、x.state 从快照日期x开始

---

如果x.changeDatejpa不支持“FROM”和“SELECT”子句中的子查询，您必须更改查询并将子查询放在“WHERE”子句中。请帮助我翻译查询：选择t.order\u state、t.claim\u number、t.id FROM SELECT*FROM t\u repair\u order WHERE claim='SERCON201465't WHERE t t t t t.order\u state='Cancel'且不存在从select*from t_repair_order中选择1，其中claim_number='SERCON201465'tt，其中tt.id>t.id，tt.order_state t.order_state；

SELECT sd

    sd.changeDate = (SELECT max(x.changeDate) FROM SnapshotDates x WHERE x.viewId = ds.viewId AND x.state = ds.state)

SELECT m FROM Professor m WHERE (SELECT COUNT(e) FROM Professor e WHERE e.manager = m) > 0

select k From Kredit k
