Converting multiple rows into a single comma separated row

Recently, I have been bitten by the MSDN forums bug. I enjoy spending time in the SSAS and SSRS forums, and the learning that I take out from there is tremendous. Initially, I just used to read and learn, while now I reply to a lot of posts too (just the simple ones, keep the tough ones for the experts to solve ;) ).

So the other day, there was this post - how can you convert multiple rows into a single comma separated row? For eg,

This can be done by the FOR XML command.

select State, (
select City + ',' as [text()]
from tableA soi
where soi.State=t.State
order by City
for xml path( '' )
)
from tableA s )t

A handy command, especially because you don't have to use stored procedures to achieve the result.

Stagnation

Well it's been quite a while since I posted anything here and quite frankly it's been quite a while since I found anything worth posting. My work occupies most of my time and it seems like I have lost that zeal to learn and try out new stuff. So,as part of this year's resolution, I have decided to hit the books again! Hopefully you will see a new post coming from me soon.

Meanwhile, I just thought of sharing this link with all of you. I hit this link during my inital training days and have found this quite useful.
