用于将字节列转换或显示为MB的SQL查询？

Question

我有一个查询

select 
   sourceIP, SUM(sourceBytes) 
from 
   flows 
where 
   sourceBytes > 1000000 
group by 
   sourceIP

此查询将带来在特定时间范围内在所有流中发送超过100万字节的IP地址，您必须输入

结果类似于

------------------------------------
| sourceIP       | SUM_sourceBytes |
------------------------------------
| 64.124.201.151 |   4282590.0     |
| 10.105.2.10    |   4902509.0     |
| 10.103.70.243  |   2802715.0     |
| 10.103.77.143  |   3313370.0     |
| 10.105.32.29   |   2467183.0     |
| 10.105.96.148  |   8325356.0     |
| 10.103.73.206  |   1629768.0     |
------------------------------------

我希望源字节显示为MB格式。我需要嵌套查询吗？感谢。

Answer 1

使用此表达式。 CONCAT是SQL Server 2012+并处理数据类型

 ...CONCAT(SUM(sourceBytes) / 1048576.0, 'MB')..

示例：

SELECT
    sourceIP, CONCAT(SUM(sourceBytes) / 1048576.0, 'MB')
FROM
    (VALUES ('10.105.2.10', 4902509.0), ('10.103.70.243', 2802715.0))
    AS flows (sourceIP, sourceBytes)
WHERE 
    sourceBytes > 1000000
GROUP BY
    sourceIP;

否则，您想要的预期输出是什么＆gt;
