Answer 1

您可以使用PIVOT。

查詢

select userid, 
[date], 
[job], 
[address] 
from 
(
    select userid,name,[value] from tblName 
) 
as s 
pivot 
(
    max([value]) for [name] in ([date], [job], [address]) 
) as p;

OR

查詢

select userid, 
max(case when name = 'date' then [value] else null end) as [date], 
max(case when name = 'job' then [value] else null end) as job, 
max(case when name = 'address' then [value] else null end) as address 
from tblName 
group by userid;

Answer 2

的另一種方式，

嘗試使用Group_Concatenate和Common Table Expression

;with cte as 

(select userid, 
STUFF((
SELECT ',' + md.[value] 
FROM tblName md 
WHERE m.userid = md.userid 
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '') 
as result 
from tblName m group by m.userid 
) 

select (cast(userid as varchar(50))+','+result) as res from cte
