SQL选择多个计数（*）输出

我很难弄清楚如何才能得到一个查询，该查询提供了多少人在某个竞选活动中收到多少封信的数据。 喜欢 输出：

我编写的当前SQL用于从所有表中获取获取信息所需的所有数据

SELECT 
account.EXT_STRING0 as client_ID,
account.EXT_STRING2 as Email,
activity.TEMPLATE_NAME as Template_name,
activity.NAME as campaign_name,
activity.EXECUTION_ID, -- unique campaign sent mail id
activity.SEND_DATE,
Activity.OPEN_DATE,
Activity.CLICK_DATE
FROM  
    crmautomation.oocke1_account account 
Join 
    crmautomation.oocke1_activity activity 
    ON 
     (account.object_id = activity.rep_contact)
left JOIN 
    crmautomation.OBJ_VAL val1
       ON val1.obj_row_id = activity.CAMPAIGN_TYPE AND (val1.OBJ_VAL_ID in(4250950)) 
left JOIN 
    crmautomation.OBJ_VAL val2
       ON val2.obj_row_id = activity.CAMPAIGN_TYPE AND (val2.OBJ_VAL_ID in(4250951))
where activity.TEMPLATE_NAME= ('cabin_surprise_ne')
and activity.SEND_DATE >('2015.12.01')

我想了一些如何使用Group by获得电子邮件计数（*）-s的方法，但我不知道如何做到这一点

编辑： 下面是这个sql的输出

client_ID   Email              template_name      Execution_ID     Send_date
'343205'  random@gmail.com   Cabin_surprise_ne  0032-1fdsa-31    2015-12-14 23:08

而且此邮件尚未打开

构造查询的一种方法如下：

with cte as (
      <your query here>
     )
select cnt, count(*) as numClients, min(client_id), max(client_id)
from (select client_id, count(activity.rep_contact) as cnt
      from cte
      group by client_id
     ) x
group by cnt
order by cnt;

我仍然不完全理解这个问题。您有两个

左连接到未使用的表。这些可能会被删除，但您没有在问题中提供足够的数据结构信息。
请将示例输入和输出添加到
group by
中。您需要将
count（*）
添加到select子句中。这是非常基本的sql。因为你不知道，我听到了这本书的好消息，在10分钟内自学SQL。你使用的是哪种DBMS？Sybase IQ Client 15.4好的，我将尝试找出答案，并在周末后回来提供更多信息，但感谢你到目前为止。虽然这可能回答了问题，任何未经最少解释就发布的代码，对于您的答案的未来读者来说，可能都不是很有用。对此我深表歉意，这一点仍然是新的。基本上，在当前查询中，按客户机ID添加计数和groub，并使用另一个计数创建外部查询，但此时间组通过电子邮件…在外部查询中，您仅选择上一个计数的总和。希望这是有意义的。你可以通过点击左下角的
