i have table family

+----------------------------+ | id | name   | age | parent | |----------------------------| | 1  | father | 60  | null   | |----------------------------| | .. | ...... | ..  | .....  | | n  | luke   | 20  | n      | +----------------------------+

the column parent reference family - id. starting of father, how can select last descendant using single select query?

the long way n = select * family parent = 1 , o = select * family parent = n, etc.

do recursive query :

select @pv:=id family join (select @pv:=1)tmp parent=@pv

to last descendant use max aggregate function

select max(@pv:=id) family join (select @pv:=1)tmp parent=@pv

update : other way around. ancestor please test query 

select min(case when parent null         id         else @pv:=parent end) ancestor family join (select @pv:=3)tmp (case when parent null or id=@pv        1 else 0 end) = 1
