Question

如何在条件中转换hibernate sql查询：

String hql = "from OMRDetailsTable omrDetailsTable " +
            "where omrDetailsTable.bar_code_no not in(" +
            "select roll_no from RejectListTable rejectListTable where rejectListTable.rej_status='R') " +
            "and omrDetailsTable.roll_no not in(" +
            "select roll_no from RejectListTable rejectListTable where rejectListTable.rej_status='R') " +
            "and omrDetailsTable.omr_error in('T','U') order by omrDetailsTable.roll_no";

我尝试过转换它但会抛出此异常：could not resolve property: parent of: com.templateproject.table.OMRDetailsTable

DetachedCriteria subCriteria =     DetachedCriteria.forClass(RejectListTable.class);
  subCriteria.add(Restrictions.eq("rej_status", 'R'));
  subCriteria.setProjection(Projections.property("roll_no"));
  subCriteria.setProjection(Projections.property("error_type"));

  Criteria criteria = session.createCriteria(OMRDetailsTable.class);
  criteria.add(Restrictions.eq("omr_error", 'T'));
  criteria.add(Restrictions.eq("omr_error", 'U'));
  criteria.add(Subqueries.propertyEq("parent", subCriteria));

我的错误是什么？

您只需要一次投影

DetachedCriteria subCriteria = DetachedCriteria.forClass(RejectListTable.class);
subCriteria.add(Restrictions.eq("rej_status", 'R'));
subCriteria.setProjection(Projections.property("roll_no"));

并且，请Subqueries.notIn()使用roll_no（不是parent）

Subqueries.notIn("roll_no", subCriteria)

将hibernate查询转换为条件
