LISTAGG alternative in Oracle 10g

Question

I am kind of newbie in Oracle. Got stuck in the below: I have the below 2 tables:

Site:

**SiteID|SiteName** 
1      Sydney
2      Ne         


        

Answer 1

I just needed an alternative for listagg on oracle 10g and found one in this page https://oracle-base.com/articles/misc/string-aggregation-techniques.

just use wm_concat, albeit it is not supported by oracle and has been droped in 12c.

with the example above:

select
    p.PeopleID,wm_concat(s.SiteName)
from people p
join site s on p.SiteID = s.SiteID
group by p.PeopleID;
