sql - Select all parents records in mysql -

-

table structure:

id(int)    title(varchar)                 parent(int) 1          accessories                    0 2          man                            1 3          women                          1 4          watches                        2 5          new watches                    4 6          used watches                   5

suppose if on forth or fifth level children category, how retrieve parent categories in query. want show breadcrumbs hierarchy.

you can try with:

select @start := id 'id', title, parent table1 join  (select @start := 0) temp parent = @start , id <= 4;

note without id < 4 check, you'll full tree "top" (0) "bottom" (6).

checkout sqlfiddle, too.
