Question

I have a table with following dataset

id   name  parent  
------------------
1    xyz   NULL  
2    def   NULL  
3    mno   abc  
4    abc   NULL  
5    pqr   abc  
6    qfx   def

I would want to fetch the data in the following order:

1    abc   NULL  
3    mno   abc  
5    pqr   abc  
2    def   NULL  
6    qfx   def  
4    xyz   NULL

What I mean is ORDERing has to occur by Username but records with same parent must show together and just below the record for the parent.

I am using MySQL.

Answer 1

try this new answer:

SELECT * 
FROM table t
ORDER BY
    CONCAT(parent, name)

it concatenated the two strings so it should order like this:

abc
abcmno
abcpqr
def
defqfx
xyz
