Function to concatenate all query results in a single row comma separeted

Question

Hi All,
my version is Oracle 10.2.0.4.0
this is my query:
select distinct
table1.id
from table1,
table2,
table3
where table1.id = table2.id
and table2.id = table3.id
and table3.id = '761'
and result is:
61
18
68B
S05
S18
68
could someone provide me a function (or something else) in order to have a result like this:
61,18,68B,S05,S18,68
and call it from another query?
I appreciate your help.
Many thanks.
Alessandro

let me demonstrate it
select *
from someotherTable x
where x.FK_ID IN (select t1.id
          from table1 t1
          table2 t2,
          table3 t3
          where t1.id = t2.id
          and t2.id = t3.id
          and t3.id = 761 /* use numbers not strings for IDs! */
