Oracle Concepts -
Unlimited Amount of Tablespace Privilege
Oracle Tips by Burleson Consulting |
UNLIMITED TABLESPACE
Use an unlimited amount of any tablespace.
This privilege overrides any specific quotas assigned. If you revoke
this privilege from a user, the user's schema objects remain but
further tablespace allocation is denied unless authorized by specific
tablespace quotas. You cannot grant this system privilege to roles.

Table 13: Oracle database system privileges
As the DBA, you can access the DBA_SYS_PRIVS
view for information on the system privileges granted to users. The
format of this view is shown in Table 14.
|
Column |
Definition |
|
grantee |
Oracle login name or role that received
the privilege |
|
privilege |
The system privilege granted to the user
or role |
|
admin_option |
Indicates YES if the grantee can pass
along the privilege and NO if the grantee cannot pass along the
system privilege |
Table 14: Contents of the DBA_SYS_PRIVS data
dictionary view.
Users can see information related to them by
accessing the corresponding user view: USER_SYS_PRIVS.
Object Privileges
Object privileges define a user?s rights on
existing database objects. All grants on objects take effect
immediately.
To grant an object privilege, you must be the
owner of the object, have been granted WITH GRANT OPTION on that
object for that privilege, or have the system privilege GRANT ANY
PRIVILEGE. You can also grant access to all users by granting the
privilege to PUBLIC. Listing 37 shows the syntax for the GRANT command
used to grant a table-level object privilege.
Listing 37: Syntax for the GRANT command used
for a table-level or snapshot-level grant.
Here is an example:
GRANT select
ON bob.emp
TO derek;
As the DBA, you can access the DBA_TAB_PRIVS
view for information on the object privileges granted to users. You
should note that although it is named DBA_TAB_PRIVS, it also includes
information on views and sequences, as well as tables. Table 14 shows
the contents of this view.
|
Column |
Definition |
|
grantee |
Oracle login name or role that received
the privilege |
|
owner |
Owner of the table |
|
table_name |
Name of the table, view, or sequence |
|
grantor |
Oracle login name of the person granting
the privilege |
|
privilege |
System privilege granted to the user |
|
grantable |
Indicates YES if the grantee can pass
along the privilege and NO if the grantee cannot pass along the
system privilege |
Table 14: Contents of the DBA_TAB_PRIVS data
dictionary view.
Users can see information on objects where
they are the owner, grantor, or grantee by accessing the corresponding
user view USER_TAB_PRIVS. Users can see information for all objects
where that user or PUBLIC is the grantee with the ALL_TAB_PRIVS view.
The ALL_TAB_PRIVS view is slightly different than the USER_TAB_PRIVS
or DBA_TAB_PRIVS view. The contents of the ALL_TAB_PRIVS view are
shown in Table 15.
|
Column |
Definition |
|
grantee |
Oracle login name or role that received
the privilege |
|
grantor |
Oracle login name of the person granting
the privilege |
|
owner |
Owner of the table |
|
table_schema |
Schema of the object owner |
|
table_name |
Name of the table, view, or sequence |
|
privilege |
System privilege granted to the user |
|
grantable |
Indicates YES if the grantee can pass
along the privilege and NO if the grantee cannot pass along the
system privilege |
Table 15: Contents of the ALL_TAB_PRIVS data
dictionary view.
A table owner can grant the following object
privileges to other users:
* ALTER
* DELETE
* INDEX
* INSERT
* REFERENCES
* SELECT
* UPDATE
* EXECUTE (for stored functions, procedures
and packages)
All grants on objects and revoking of those
grants are valid immediately, even if a user is currently logged into
the database. The SELECT privilege can only be granted on tables,
views, and snapshots. The EXECUTE privilege is used for packages,
procedures and functions. Remember that packages, procedures and
functions are always executed with the permissions of the owner of
that package, procedure or function.
By granting other users INSERT, UPDATE,
DELETE, and SELECT privileges on your table, you allow them to perform
that action on the table. By granting the ALTER privilege, you can
allow another user to modify the structure of your table or create a
trigger on your table. By granting users the INDEX privilege, you can
allow them to create indexes on your table.
The REFERENCES privilege differs from the
other privileges in that is does not actually grant the capability to
change the table or data contained in the table. The REFERENCES
privilege allows users to create foreign key constraints that
reference your table.
Users can access the USER_TAB_PRIVS_RECD for
information on table privileges where that user is the grantee. The
corresponding ALL_TAB_PRIVS_RECD view includes all grants on objects
where that user or PUBLIC is the grantee. Table 16 shows the contents
of the USER_TAB_PRIVS_RECD view.
|
Column |
Definition |
|
OWNER |

|
table_name |

the privilege |
|

|
grantable |

along the privilege and NO if the grantee cannot pass along the
object privilege |
Table 16: Contents of the USER_TAB_PRIVS_RECD
data dictionary view.
Users can access the USER_TAB_PRIVS_MADE for
information on table privileges that they have granted to others. The
corresponding ALL_TAB_PRIVS_MADE view includes information on all the
grants that user has made, as well as grants by others on that user?s
objects. Table 17 shows the contents of the USER_TAB_PRIVS_MADE view.
|
Column |

the privilege |
