Multiple proxy roles in trusted session - forum topic by Capri_DR

Hi,
     Could someone please mention if we can set up multiple proxy roles for a application proxy user. We are setting query band to mention multiple roles but we are getting an error.

SET QUERY_BAND = 'PROXYUSER=PUSERA;PROXYROLE=ROLE1,ROLE2,ROLE3' for Session;

The proxy user has already been granted 5 proxy roles (via grant connect through ...) and we want to tie him with only 3 roles above.

What would be the right syntax to mention 3 proxy roles for proxy user?

Thanks!
