如何使用SQL Server返回逗号分隔的字符串？

[MyAuthorize("Home")]
public class HomeController : Controller
{ }

并让它返回如下结果：

select ID, 
(<<SomeQuery from TableB B where (B.Id = A.TableBId)>>)
from TableA A

Answer 1

您可以使用STUFF（），See Demo Here

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(data AS VARCHAR(10)) [text()]
         FROM B 
         WHERE TableBId = A.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') Comma_Output
FROM A
GROUP BY ID
