U write a function like nthis
create or replace function p1(src_id varchar(5)) return varchar2(5) as
s1 varchar2(5);
s2 varchar2(5);
p2 varchar(2);
begin
s1 := src_id;
begin
select P2 = 'F' from dual;
do while p2 = 'F'
begin
select s2 = mrg_id from ur_table
where src_id = s1;
s1 = s2
exception when no_data_found then
return s1;
end
return s1;
end
select src_id, mrg_id, p1(src_id) from ur_table;
Basically function will try to find the final src_id thru a loop. I didnt chek the function . Take it as a logic only.
I am currently working on sql server. So the syntax may be not correct. Chek it it should work

select s1 = src_id from ur_table
