複雜的查詢集成

Question

這是我正在處理的主要查詢，這些查詢即將完成。我需要添加的最後一件事是達到客戶端的最後10個電話號碼。

select distinct 
     max(case when isnull(d.lastname,'')='' then d.name 
      else d.firstname+' '+(case when isnull(d.middlename,'')='' then '' else d.middlename+' ' end)+d.lastname+ 
       (case when isnull(d.suffix,'')='' then '' else ' '+d.suffix end) end) 
     ,max(isnull(d.street1,p.street1)) 
     ,max(isnull(d.street2,'')) 
     ,max(d.city) 
     ,max(isnull(d.state,p.state)) 
     ,max(isnull(d.zipcode,p.zipcode)) 
     ,max(dbo.stripnondigits(isnull(d.ssn,p.ssn))) 
     ,'Add' 
     ,'Primary Secondary Flag' 
     ,max(m.number) 
     , as 'phone1' 
     , as 'phone2' 
     , as 'phone3' 
     , as 'phone4' 
     , as 'phone5' 
     , as 'phone6' 
     , as 'phone7' 
     , as 'phone8' 
     , as 'phone9' 
     , as 'phone10' 
    from people p 
    inner join master m 
     on p.accountid = m.number 
    inner join d_table d on p.debtorid=d.debtorid and isnull(d.jobname,'')='' 
group by p.pid 

我需要的電話*列與最近的電話號碼是phone1到下一個最近的是phone2等來填充。

下面是爭奪最後的10個電話號碼查詢：

select ah.rownumber, ah.number, ah.dateadded, ah.phonenumber 
from (SELECT ROW_NUMBER() OVER (partition by number order by dateadded desc) as 'rowNumber', number, dateadded, phonenumber 
      FROM phones_master) ah 
where rownumber <=10 
order by ah.number, ah.rownumber 

此查詢將返回最多（1〜10）電話號碼的人。

上ah.number = m.number

這組我不知道如何將這兩個查詢合併成一個。有些帳戶會返回1個電話號碼，有些可能會返回10.是否有可能整合這兩個查詢？第一個是很久以前另一個人寫的，我只需要在其中創建第二個查詢。

我覺得可能是在這裏築巢的不必要的水平，但這應該工作：
