Consider the case : In a database , I have two users A and B and their corresponding schema.
I want to know , How can I get the information : what permissions are there
Login into the database. then run the below query
select * from dba_role_privs where grantee = 'SCHEMA_NAME';
All the role granted to the schema will be listed.
Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.
