我们正在尝试为下面创建特定于hibernate的查询
lSession.createQuery(lQueryString.toString());
............
INSERT INTO EMPLOYEE_HISTORY (emp_status,
createdBy,
releasedate,
year)
SELECT CASE n.emp_Status WHEN 0 THEN 'Draft' ELSE 'Final' END,
m.createdBy,
m.releasedate,
m.year
FROM EMPLOYEE m, (SELECT COUNT (1) EMPLOYEE_HISTORY b,EMPLOYEE a where a.emplid=b.emplid and a.year=b.year and b.year=2012 and a.doc_id='XYZ') n
where a.doc_id='xyz'
getting following exception,I guess it because of below statement in query
(SELECT COUNT (1) EMPLOYEE_HISTORY b,EMPLOYEE a where a.emplid=b.emplid and a.year=b.year and b.year=2012 and a.doc_id='XYZ') n
org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ( near line 1, column 374
INSERT INTO EMPLOYEE_HISTORY (emp_status,

如果有任何建议/输入,请提供。

看起来像是将SQL而不是HQL传递给Session.createQuery(...)方法。
例如:
INSERT INTO EMPLOYEE_HISTORY (...)
'EMPLOYEE_HISTORY'应该是实体类名称(如EmployeeHistory)而不是表名。
同样在HQL中,您可以使用实体中定义的引用来完成关联,避免通过ID进行隐式连接,就像您在此处一样
where a.emplid=b.emplid and ...
考虑以上网址的示例:
select mother from Cat as cat join cat.mother as mother where cat.name = ?
