Java JPA查询异常意外(

嗨，这是我的实体StudentEntity.java

  @Entity
  @NamedQueries({
    @NamedQuery(name="totalStudentSQLQuery",
                query="select count(*) as MAX_STUDENT from tblstudent"),    
    @NamedQuery(name="queryForPagination",
                query="SELECT s.studentid AS studentid, s.studentname AS studentname, s.contactno AS contactno, s.deptid AS deptid "+
                        "FROM (SELECT Row_number() OVER() AS row_num, studentid, studentname, contactno, deptid FROM   tblstudent order by studentId asc) s" +
                        " WHERE  s.row_num >=:minRow AND s.row_num <=:maxRow")
  })
  @Table(name="TBLSTUDENT")
  public class StudentEntity implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 100034222342L;

    @Id
    @Column(name="STUDENTID")
    private Integer studentId;

    @Column(name="STUDENTNAME")
    private String studentName;

    @Column(name="CONTACTNO")
    private String contactNumber;
    .....
    .....

  }     

我使用Hibernate 4.0 JAR作为持久性提供程序，并使用JPA

我的persistense.xml如下所示

  <?xml version="1.0" encoding="UTF-8"?>
  <persistence xmlns="http://java.sun.com/xml/ns/persistence"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
               version="2.0">
    <persistence-unit name="forPractise" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>jdbc/app</jta-data-source>
        <class>com.entity.StudentEntity</class>
        <class>com.entity.DeptEntity</class>
        <properties>
                <property name="hibernate.dialect"  value="org.hibernate.dialect.DerbyDialect"  />
                <property name="hibernate.show_sql" value="true" />
                <property name="hibernate.format_sql" value="true" />               
            </properties>
    </persistence-unit>
  </persistence>

现在，当我创建这个项目的war文件并尝试在Glassfish服务器中部署时，我得到了一个错误 意外令牌：

---

org.hibernate.hql.internal.ast.QuerySyntaxException:意外标记：第116列第1行附近[选择s.studentid作为studentid，s.studentname作为studentname，s.contactno作为contactno，s.deptid作为deptid从选择行编号到作为行编号，studentid，studentname，contactno，deptid从TblStudentOrder按studentid asc s排序，其中s.Row_num>=：minRow和s.Row_num看起来像是在使用标准SQL查询。对于NamedQuery，您可以ave使用JPA-QL定义查询。

如果要使用经典的SQL数据库dipendent，必须使用 @命名为“运动装备”
