Question : Get view privileges granted to roles

We can get table privileges granted to roles by:
SELECT DBMS_METADATA.GET_GRANTED_DDL('OBJECT_GRANT', role) from ROLE_TAB_PRIVS;
But how to get view privileges granted to roles?

Answer : Get view privileges granted to roles

I add this view to the data dictionary, then select from it.  Note that it has a column "table_name" but that column includes views, procedures, etc.  You could change that "object_name" instead and also get the column "object_type" from sys.obj$.

create or replace view table_privs (GRANTEE,
OWNER,
TABLE_NAME,
GRANTOR,    
PRIVILEGE,
GRANTABLE,
GRANT_ID)
as select substr(ue.name,1,24), substr(u.name,1,13),
 substr(o.name,1,30), substr(ur.name,1,13), substr(tpm.name,1,10),
decode(oa.option$, 1, 'YES', 'NO'), oa.sequence#
from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
table_privilege_map tpm
where oa.obj# = o.obj#
and oa.grantor# = ur.user#
and oa.grantee# = ue.user#
and oa.col# is null
and u.user# = o.owner#
and oa.privilege# = tpm.privilege
and (userenv('SCHEMAID') in (oa.grantor#, oa.grantee#, o.owner#)
 or oa.grantee# = 1) -- grantee# 1 = "PUBLIC";
--
create public synonym table_privs for sys.table_privs;
grant select on table_privs to public;
