Getting distinct column with multiple columns

if we have table id, name, age

the requirements is id has different and redundatnt data

We want the distinct column with corresponding rows. this is highly useful

SELECT id,
role_id_fk,
privilege_id_fk
FROM (SELECT id,
role_id_fk,
privilege_id_fk,
Row_number() OVER(PARTITION BY role_id_fk ORDER BY id) rn
FROM tbl_roles_privileges) t
WHERE rn = 1
