i am looking for some advice on what is the best approach to get this done :)
my datababase holds a table categories
with the columns
|category_id|category_name|category_parent_id|
i am showing my users a html sortable table with the following columns
|category_id|category_name|category_parent_name|
so what i want, is to do a ORDERBY on the category_parent_names so i would like to have a temp extra column like
|category_id|category_name|category_parent_id|category_parent_name|
so i can sort on category_parent_name.
What is the best way to go on this?
