Question

I deleted my other post for the same question and reposting a new one as I feel the other question is confusing. Please pardon me for the duplicate. Hoping this would get some traction

Here is my table A

Id   Name
1    Name1
1    Name2
2    Name3
2    Name4
2    Name5

Table B:
Id FileName
1  file1
2  File2

I need the output combined with table B as

 Id FileName Name
 1  file1    Name1,Name2
 2  file2    Name3,Name4,Name5

I tried couple of approaches with COALESE , they work stand-alone, but only when I input Id=<>.

How do I do this combined with two tables?

Please let me know if I can explain more. And I apologize for my last post.

Answer 1

SELECT Id, FileName,
(SELECT Name+',' FROM A WHERE A.Id = B.Id FOR XML PATH('')) Name
FROM B

There is on your responsibility to strip the last comma 😎

Hint:

SELECT Id, FileName,
STUFF((SELECT ','+Name FROM @A a WHERE A.Id = B.Id FOR XML PATH('')), 1, 1, '') Name
FROM @B b
