Question

我试图按照文档中的示例进行操作 http://docs.jboss.org/hibernate/orm/3.3 ... tch-direct

但是在我的服务器日志中出现以下错误：

SEVERE：org.hibernate.QueryException：查询必须以SELECT或FROM开头：update [update hibernate.TbUser u set u.vcUserName =：userName，u.vcUserPsw =：userPsw，u.vcUserFirstName =：firstName ，u.vcUserLastName =：lastName，u.vcUserMiddleName =：middleName，u.vcEmailAddress =：email，u.vcPhoneNumber =：phone，u.dtTerminatedDate =：termDate，u.dtHireDate =：hireDate，u.dtUpdTime =：updTime， u.iUpdUserId =：userId，其中iUserId =：id]

这表示我需要使用SELECT或FROM启动查询，但该示例在更新查询中使用Update，因此我不明白问题所在。

有谁能告诉我一个如何做Update ???的例子？文件显然没有。感谢。

以下是我要执行的代码：

public int updateUser( String userName, String passwd, String firstName, String middleName, 
        String lastName, String email, String phone, Date termDate, Date hireDate, int id )
{
    int status = 0;
    try {
        org.hibernate.Transaction tx = session.beginTransaction();
        String cmd = "update TbUser u set u.vcUserName = :userName, "+
                "u.vcUserPsw = :userPsw, u.vcUserFirstName = :firstName, "+
                "u.vcUserLastName = :lastName, u.vcUserMiddleName = :middleName, "+
                "u.vcEmailAddress = :email, u.vcPhoneNumber = :phone, "+
                "u.dtTerminatedDate = :termDate, u.dtHireDate = :hireDate, "+
                "u.dtUpdTime = :updTime, u.iUpdUserId = :userId where iUserId = :id";
        Query q = session.createQuery( cmd );
        q.setString("userName", userName);
        q.setString("userPsw", passwd);
        q.setString("firstName", firstName);
        q.setString("middleName", middleName);
        q.setString("lastName", lastName);
        q.setString("email", email);
        q.setString("phone", phone);
        q.setDate("termDate", termDate);
        q.setDate("hireDate", hireDate);
        q.setDate("updTime", new Date());
        q.setInteger("id", id);
        status = q.executeUpdate();
        tx.commit();
    }
    catch( Exception e ) {
        e.printStackTrace();
        status = -1;
    }
    return status;
}

查看此页面here，看起来您需要在类路径中包含antlr * .jar并使用其他解析器org.hibernate.hql.ast.ASTQueryTranslatorFactory。

尝试使用该库，看看你如何去。

尝试做Hibernate更新 - 有人能指出我正确的方向吗？
