groupname not coming in the radacct table

Hi folks, I am running *FreeRADIUS 3.0.13 *and missing the groupname in the radacct table. Apart from groupname everything else seems to be working fine. Any idea how can i add it ? I dont think i can add into the account insert insert query. but i tried it and its empty there as well. i tried in /etc/raddb/mods-config/sql/main/mysql/queries.conf
