Question

我是HQL的新手，想要使用INSERT stmt将数据直接插入数据库。使用以下代码时： CompanyMaster是型号名称（ CompanyMaster.java ）

public void insertCompanyData(CompanyMaster company) {
    logger.info("Entering insertCompanyData");

    Session session = null;
    try{
        session = getSession();
        String hql = "INSERT INTO CompanyMaster (CompName,description,status) SELECT  (company.getCompName(),company.getDescription(),company.getStatus())";
        //String hql = "INSERT INTO CompanyMaster company(CompName,description,status) VALUES (company.getCompName(),company.getDescription(),company.getStatus())";
        Query query = session.createQuery(hql);
        //query.setString("groupId", groupId);
        query.executeUpdate();
    } finally{
        releaseSession(session);
    }

    logger.info("Exiting insertCompanyData");
}

我收到这样的错误

请建议如何纠正此错误...

Answer 1

查询的选择部分必须是有效的HQL选择查询，返回与insert子句中指定的列匹配的列。

如果要从内存中的值插入新行，只需使用persist()：

CompanyMaster c = new CompanyMaster();
c.setName(someName);
...
session.persist(c);

在HQL中插入stmt
