Hi Guys,

Below is the scenerio:

Table A
id name parent id
1 a 2
2 b 3
3 c null
4 d 3
5 e 1

Need output like:

b c
c Null

Thanks in advance.

SELECT t2.Name, t1.Name AS ParentName
FROM dbo.TableA AS t1
INNER JOIN dbo.TableA AS t2 ON t2.ID = t1.ParentID

N 56°04'39.26"
E 12°55'05.63"

Perhaps this would give the desired output

SELECT
t1.Name,t2.Name as parentName
FROM @TableA AS t1
Left JOIN @TableA AS t2 ON t1.ParentID = t2.ID
