Oracle NoSQL Database provides a set of declarative language of security operations, including the commands allowing to create, drop, show, grant or revoke roles to or from users, and grant or revoke privileges to or from roles. All these statements can be executed via the “execute” command in Admin CLI, or the API of KVStore.execute() or KVStore.executeSync().
CREATE ROLE role_name
Where, role_name is the name of the role, which
is case insensitive.
For example,
kv-> execute 'CREATE ROLE administrator' Statement completed successfully
DROP ROLE role_name
Where, role_name is the name of the role, which
is case insensitive.
For example,
kv-> execute 'DROP ROLE administrator' Statement completed successfully
SHOW [AS JSON] ROLES | ROLE role_name
Where, role_name is the name of the role.
List all available role names by running 'SHOW ROLES', or view the detailed information of a role if the role name is specified.
For example,
kv->execute 'SHOW ROLES' role:name=dbadmin role:name=public role:name=readonly role:name=readwrite role:name=sysadmin role:name=writeonly
The detailed information of a role can be viewed by specifying the role name:
kv->execute 'SHOW ROLE dbadmin' name=dbadmin assignable=true readonly=true granted-privileges=[SYSDBA, DBVIEW]
Object privileges will appear in the form of PRIVILEGE(obj). For example, privilege of READ_TABLE on table 'emp' will appear as:
kv->execute 'CREATE ROLE emptablereader' kv->execute 'GRANT READ_TABLE ON emp TO emptablereader' kv->execute 'SHOW ROLE emptablereader' name=emptablereader assignable=true readonly=false granted-privileges=[READ_TABLE(emp)]
GRANT { grant_roles | grant_system_privileges
| grant_object_privileges }
grant_roles ::= role [, role]... TO { USER user | ROLE role }
grant_system_privileges ::=
{system_privilege | ALL PRIVILEGES}
[,{system_privilege | ALL PRIVILEGES}]...
TO role
grant_object_privileges ::=
{object_privileges| ALL [PRIVILEGES]}
[,{object_privileges| ALL [PRIVILEGES]}]...
ON object TO role
where:
role
The role that is granted.
user
The user to which the privileges are granted.
system_privileges
The system privileges that are granted.
object_privileges
The object privileges that are granted.
object
The object on which the privilege is granted. Currently only table privileges are supported.
ALL PRIVILEGES
Grants all of the system privileges. This is a shortcut for specifying all system privileges.
ALL [PRIVILEGES]
Grants all object privileges defined for the object. The keyword PRIVILEGES is provided for semantic clarity and is optional.
For example, to grant a role 'manager' to another role 'employee':
kv-> execute 'GRANT EMPLOYEE TO ROLE manager' kv-> execute 'GRANT MANAGER TO USER Kate' Statement completed successfully
If you repeat the command:
kv-> execute 'GRANT employee to ROLE manager'
You will receive an error of "Could not recursively grant role employee to role manager" because this would lead to a cyclic definition of role manager.
The user can now add new privileges to their defined role. For example:
kv-> execute 'GRANT READ_ANY TO Kate'
For example, to grant read permission on table T1 to Kate:
kv-> execute 'GRANT READ_TABLE on T1 TO Kate'
See also notes on granting table privileges in Table Ownership.
REVOKE { revoke_roles | revoke_system_privileges
| revoke_object_privileges}
revoke_roles ::= role [, role]... FROM { USER user | ROLE role }
revoke_system_privileges ::=
{ system_privilege | ALL PRIVILEGES }
[, {system_privilege | ALL PRIVILEGES}]...
FROM role
revoke_object_privileges ::=
{ object_privileges| ALL [PRIVILEGES] }
[, { object_privileges | ALL [PRIVILEGES] }]...
ON object FROM role
where:
role
The role to revoke.
user
The user from which the privileges are revoked.
system_privileges
The system privileges to revoke.
object_privileges
The object privileges to revoke.
object
The table from which the privileges are revoked. Currently, the only objects supported are tables.
ALL PRIVILEGES
Revokes all of the system privileges that have been granted to the revokee.
ALL [PRIVILEGES]
Revokes all object privileges defined on the object from the revokee. The keyword PRIVILEGES is provided for semantic clarity and is optional.
For example, to revoke role 'employee' from role 'manager':
kv-> execute 'REVOKE employee FROM ROLE manager' Statement completed successfully
To revoke the role 'manager' from user 'Kate':
kv-> execute 'REVOKE manager FROM USER Kate' Statement completed successfully
