wrap your query that returns the BRAND column in an inline view that returns distinct values

something like this...

select
rtrim (xmlagg (xmlelement (e, BRAND || ',')).extract ('//text()'), ',') Purchase_BRAND
from (select distinct brand from yourtable)

I ran into issues when trying to perform a CTAS statement to a table. Ultimately has to use the .getclobval() statement and remove the RTRIM of the ',' to move on.
