spring数据本机查询不起作用

我有一个本地查询,如下所示:

@Query(value = "SELECT * FROM (" +
        "    SELECT result.*, ROWNUM rn FROM (" +
        "        SELECT tmp.* FROM (" +
        "            SELECT " +
        "                e.id, " +
        "                e.employee_number, " +
        "                d.name, " +
        "                d.surname " +
        "            FROM employee e INNER JOIN detail d ON e.id_detail = d.id " +
        "            WHERE e.status = :status " +
        "        ) tmp " +
        "        ORDER BY :sortColumn :sortDirection " +
        "    ) result " +
        "    WHERE ROWNUM <= (:pageIndex + :pageSize) " +
        ") " +
        "WHERE rn > :pageIndex "
        , nativeQuery = true)
ArrayList<Object> getEmployeeDetails( @Param("status") EmployeeStatus status,
                                           @Param("pageSize") int pageSize,
                                           @Param("pageIndex") int pageIndex,
                                           @Param("sortDirection") String sortDirection,
                                           @Param("sortColumn") String sortColumn);

我得到以下错误:

org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
// ...
Caused by: org.hibernate.exception.SQLGrammarException: could not extract ResultSet
// ...
Caused by: java.sql.SQLSyntaxErrorException: ORA-01745: invalid host/bind variable name

我尝试的是不同的返回类型(最终没有找到要使用的返回类型),用 @Param() 注解。
查询本身确实有效-我直接在数据库中尝试了它,但在spring中处理它时遇到了问题。
查询本身便于调试:

SELECT * FROM (
    SELECT result.*, ROWNUM rn FROM (
        SELECT tmp.* FROM (
            SELECT
                e.id,
                e.employee_number,
                d.name,
                d.surname
            FROM employee e INNER JOIN detail d ON e.id_detail = d.id
            WHERE e.status = 'status'
        ) tmp
        ORDER BY tmp.name desc
    ) result
    WHERE ROWNUM <= (0 + 5)
)
WHERE rn > 0

编辑:

我更新了这个问题,并建议删除所有 \n 并检查是否缺少空格。
普通查询,不使用任何参数也可以工作,但是当我开始通过 @Param() 注解或绑定( ?1 )它停止工作给我上面更新的错误。

如果 EmployeeStatusenum 你必须在你的查询中使用这个 WHERE e.status = :#{#status.name()}
