Query Regarding rollback statement.....

hi all,

can anyone tell me the functionality of rollback in this statement?........

replace macro ops_dbs.del_nei_ric (
ric varchar(17)
)
as (
rollback 'Temp Ric does not exists ' where :ric not in
(
select ric
from adb_prod_t.traded_item_on_market
where ric = :ric
and ti_on_market_id > 100000000
);
);

regards,
dinesh
