Is it possible to "merge" the values of multiple records into a single field without using a stored
- by j0rd4n
A co-worker posed this question to me, and I told them, "No, you'll need to write a sproc for that".  But I thought I'd give them a chance and put this out to the community.
Essentially, they have a table with keys mapping to multiple values.  For a report, they want to aggregate on the key and "mash" all of the values into a single field.  Here's a visual:
---  -------
Key  Value
---  -------
1    A
1    B
1    C
2    X
2    Y
The result would be as follows:
---  -------
Key  Value
---  -------
1    A,B,C
2    X,Y
They need this in SQLServer 2005.  Again, I think they need to write a stored procedure, but if anyone knows a magic out-of-the-box function that does this, I'd be impressed.
