  3. 将创建外表语句中的参数ACCESS_KEY和SECRET_ACCESS_KEY替换为实际值,然后在客户端工具中执行替换后的语句创建外表。

    ACCESS_KEY和SECRET_ACCESS_KEY的值,请参见本文档的创建访问密钥(AK和SK)章节进行获取,然后将获取到的值替换到创建外表语句中。

  4. 使用INSERT命令导入数据。

    --查询所有记录,且按字母升序排列。
    SELECT r_reason_desc FROM tpcds.reason ORDER BY r_reason_desc;
    
    --根据查询条件过滤,并对结果进行分组。
    SELECT r_reason_id, AVG(r_reason_sk) FROM tpcds.reason GROUP BY r_reason_id HAVING AVG(r_reason_sk) > 25;
