if @ image above... want email jmgr@gmail.com first 3 rows ( user_name john). , want email mmgr@gmail.com 4th row (where user_name mike) , forth.

the image above have far.

you want use listagg() function:

select email_id,        listagg(db_name || ' ' || sc_name || ' ' || ro_name, ', ') within group(order db_name, sc_name, ro_name) message  table  group email_id
