SQL查询将多个组分组

Question

我正在解析一些IIS服务器日志(使用LogParser),我在创建一个查询时遇到了一些麻烦,该查询将为每种类型的浏览器(用户代理)提供总计数.

这是我目前的查询:

SELECT COUNT(*) as totalHits, CS(User-Agent) as browser
FROM E:\Logs\ex111101.log
WHERE (CS(User-Agent) LIKE '%ipad%' 
       OR CS(User-Agent) LIKE '%iphone%' 
       OR CS(User-Agent) LIKE '%blackberry%'
       OR CS(User-Agent) LIKE '%windows cs%'
       OR CS(User-Agent) LIKE '%android%')
AND cs-uri-stem LIKE '%.asp%'
GROUP BY browser
ORDER BY totalHits DESC

这给我一个像我想要的用户代理列表,并给我每组浏览器的命中数:

Total Hits | Browser
467        | AndroidA 
45         | AndroidB 
23         | BlackberryC
233        | BlackberryD

我想要的是这个:

Total Hits | Browser 
512        | Android 
256        | Blackberry

所有Android条目在通用Android行下计算和汇总的位置.在这种情况下,Android的总点击数将是467 + 45,黑莓将是233 = 33等.

从那里我想为每个浏览器提供一个百分比列,以便我可以用百分比表示总命中数.

任何帮助表示赞赏.谢谢!

*更新

遵循以下建议,但必须进行一些调整才能使LogParser正确执行.由于某种原因,Log Parser不喜欢CASE语句中的LIKE关键字.以下工作正常:

select
case strcnt(TO_LOWERCASE(cs(user-agent)),'android') WHEN 1 THEN 'Android' else
case strcnt(TO_LOWERCASE(cs(user-agent)),'ipad') WHEN 1 THEN 'iPad' else
case strcnt(TO_LOWERCASE(cs(user-agent)),'blackberry') WHEN 1 THEN 'Blackberry' else
case strcnt(TO_LOWERCASE(cs(user-agent)),'windows ce') WHEN 1 THEN 'Windows' else
case strcnt(TO_LOWERCASE(cs(user-agent)),'iphone') WHEN 1 THEN 'iPhone' 
ELSE 'Non-Mobile' End End End End End as Browser,
count(*) as TotalHits
from MYLOG
group by Browser
order by TotalHits desc

尝试

select
      case when cs(User-Agent) like "%android%" then "Android"
           when cs(User-Agent) like "%black%" then "Blackberry"
           when cs(User-Agent) like "%windows%" then "Windows"
           when cs(User-Agent) like "%iphone%" then "iPhone"
           else "Other" end as Browser,
      count(*) as TotalHits
   from
      YourTable.logFile
   group by
      Browser
   order by
      TotalHits desc

按顺序列顺序排序而不是重复复制整个案例/何时计数(*)...因为只有两列,没有问题......
