Sql 如何在Oracle数据库的单个列中连接case语句值的值

select
 case
   when s.X344731='Y' then 'Property Tax Assessment'
   when s.X344732='Y' then 'Property Tax Payment'
   when s.X344733='Y' then 'Birth and Death Certificate'
   when s.X344734='Y' then ' Trade License'
   when s.X344735='Y' then ' Complaints/Grievance Redressal'
   when s.X344736='Y' then 'Water Connection'
   when s.X344737='Y' then 'Sewerage Connection'
   when s.X344738='Y' then 'Online Building Plan Approval System'    
   when s.X344739='Y' then ' Fire NOC'    
   when s.X3447310='Y' then ' NOC (Others)'    
   when s.X3447311='Y' then 'Certificates (Others)'    
   when s.X3447312='Y' then 'User Charges (water charges, parking fee, advertisement charges, electricity charges etc. )'    
   when s.X3447313='Y' then 'All of the above'    
   when s.X3447314='Y' then 'None of the above'    
   else 'Not Answered' end as municipal_services_do_you_use    
from lime_survey_988773 s 
left join lime_tokens_988773 t 
on (s.token=t.token)     
where s.submitdate is not null 
  and user_id=143561; 

我想把这三个‘物业税判断’、‘物业税缴纳’和‘出生和死亡证明’的价值联系起来，看起来是这样的:

User_id  Municipal_Services_Do_you_use                                                      State
142351   ('Property Tax Assessment', 'Property Tax Payment','Birth and Death Certificate')  Delhi
