MYSQL output in tree format OR Adding level (Parent-Child)

Question

Below is what I have in my table.

myTable

++++++++++++++++++++
Parent   +  Child
++++++++++++++++++++
  C1     +    G1
  C1     +    G2
  C1     +          


        

Answer 1

If you restructured your table a bit you could use something like:

  SELECT Child,CONCAT(LPAD('',Clevel,' '),Child),etc from tablename

The restructuring is that you would need the root node in as a row with parent node of 0. You can add your own ordering with parent / child / C level to get the sequence as desired.

I know this is from a few years back, but it might save someone else some effort!
