Open original thread
Hi Everyone,

Good day.

Can you help on how to achieve the result in SQL select query?

dID   dName       sdID
1    XYZ Company   0
2    AA dept       1
3    BB dept       1
4    CC dept       1
5    AA.section    2
6    BB.section    3
7    CC.section    4

Expected query result
dID   dName       sdID     NewColumn
1    XYZ Company   0          
2    AA dept       1      XYZ Company
3    BB dept       1      XYZ Company
4    CC dept       1      XYZ Company
5    AA.section    2      AA dept
6    bb.section    3      BB dept
7    CC.section    4      CC dept 

The sdID will lookup to dID then the corresponding dName shows in NewColumn.

What I have tried:

Can't find related case in the net.
Thanks in advance.
