Working by group by for grouping data into string format
- by Shantanu Gupta
I have a table that contains some data given below. It uses a tree like structure
i.e.
Department
SubD1, SubD2 .....
PreSubD1, PreSubD1... PreSubD2, PreSubD2...
pk_map_id preferences ImmediateParent Department_Id
-------------------- -------------------- -------------------- --------------------
20 14 5 1
21 15 5 1
22 16 6 1
23 9 4 2
24 4 3 2
25 24 20 2
26 25 20 2
27 23 13 2
I want to group my records on behalf of department then immediate parent then preferences each seperated by ','
i.e.
department Immediate Parent preferences
1 5,6 14,15,16
2 4,3,20,13 9,4,24,25,23
and this table also
Immediate parent preferences
5 14,15
6 16
4 9
3 4
20 24,25
13 13
In actual scenario all these are my ids which are to be replaced by their string fields.
I am using sql server 2k5
