Use the GRANT
statement to grant:
Roles to users and roles. The granted roles can be either local or external. For information on predefined roles, refer to Oracle Database Security Guide.
System privileges to users and roles. Table 18-1 lists the system privileges (organized by the database object operated upon).
Object privileges for a particular object to users, roles, and PUBLIC
. Table 18-2 lists object privileges and the operations that they authorize.
Note:
Global roles (created withIDENTIFIED
GLOBALLY
) are granted through enterprise roles and cannot be granted using the GRANT
statement.Notes on Authorizing Database Users You can authorize database users through means other than the database and the GRANT
statement.
Many Oracle Database privileges are granted through supplied PL/SQL and Java packages. For information on those privileges, refer to the documentation for the appropriate package.
Some operating systems have facilities that let you grant roles to Oracle Database users with the initialization parameter OS_ROLES
. If you choose to grant roles to users through operating system facilities, then you cannot also grant roles to users with the GRANT
statement, although you can use the GRANT
statement to grant system privileges to users and system privileges and roles to other roles.
Note on Oracle Automatic Storage Management A user authenticated AS
SYSASM
can use this statement to grant the system privileges SYSASM
, SYSOPER
, and SYSDBA
to a user in the Oracle ASM password file of the current node.
A GRANT
operation to grant object privileges on an editionable object actualizes the object in the current edition. See Oracle Database Advanced Application Developer's Guide for more information about editions and editionable objects.

REVOKE for information on revoking grants
To grant a system privilege, one of the following conditions must be met:
You must have been granted the GRANT
ANY
PRIVILEGE
system privilege. In this case, if you grant the system privilege to a role, then a user to whom the role has been granted does not have the privilege unless the role is enabled in user's session.
You must have been granted the system privilege with the ADMIN
OPTION
. In this case, if you grant the system privilege to a role, then a user to whom the role has been granted has the privilege regardless whether the role is enabled in the user's session.
To grant a role, you must either have been granted the role with the ADMIN
OPTION
or have been granted the GRANT
ANY
ROLE
system privilege, or you must have created the role.
To grant an object privilege, you must own the object, or the owner of the object must have granted you the object privileges with the GRANT
OPTION
, or you must have been granted the GRANT
ANY
OBJECT
PRIVILEGE
system privilege. If you have the GRANT
ANY
OBJECT
PRIVILEGE
, then you can grant the object privilege only if the object owner could have granted the same object privilege. In this case, the GRANTOR
column of the DBA_TAB_PRIVS
view displays the object owner rather than the user who issued the GRANT
statement.
(grant_system_privileges::=, grant_object_privileges::=)
(on_object_clause ::=, grantee_clause ::=)
on_object_clause ::=
grantee_clause ::=
Use these clauses to grant system privileges.
Specify the system privilege you want to grant. Table 18-1 lists the system privileges, organized by the database object operated upon.
If you grant a privilege to a user, then the database adds the privilege to the user's privilege domain. The user can immediately exercise the privilege. Oracle recommends that you only grant the ANY
privileges to trusted users.
If you grant a privilege to a role, then the database adds the privilege to the privilege domain of the role. Users who have been granted and have enabled the role can immediately exercise the privilege. Other users who have been granted the role can enable the role and exercise the privilege.
If you grant a privilege to PUBLIC
, then the database adds the privilege to the privilege domains of each user. All users can immediately perform operations authorized by the privilege. Oracle recommends against granting system privileges to PUBLIC
.
Oracle Database provides the ALL
PRIVILEGES
shortcut for granting all the system privileges listed in Table 18-1, except the SELECT
ANY
DICTIONARY
, ALTER
DATABASE
LINK
, and ALTER
PUBLIC
DATABASE
LINK
privileges.
Specify the role you want to grant. You can grant an Oracle Database predefined role or a user-defined role.
If you grant a role to a user, then the database makes the role available to the user. The user can immediately enable the role and exercise the privileges in the privilege domain of the role.
In the case of a secure application role, you need not grant such a role directly to the user. You can let the associated PL/SQL package do this, assuming the user passes appropriate security policies. For more information, see the CREATE
ROLE
semantics for USING package and Oracle Database Security Guide
If you grant a role to another role, then the database adds the privilege domain of the granted role to the privilege domain of the grantee role. Users who have been granted the grantee role can enable it and exercise the privileges in the granted role's privilege domain.
If you grant a role to PUBLIC
, then the database makes the role available to all users. All users can immediately enable the role and exercise the privileges in the privilege domain of the role.
See Also:
Oracle Database Security Guide for information on the Oracle predefined roles
CREATE ROLE for information on creating a user-defined role
This clause is valid only when granting system privileges, not when granting object privileges. Use the IDENTIFIED
BY
clause to specifically identify an existing user by password or to create a nonexistent user. This clause is not valid if the grantee is a role or PUBLIC
. If the user specified in the grantee_clause
does not exist, then the database creates the user with the password and with the privileges and roles specified in this clause.
See Also:
CREATE USER for restrictions on usernames and passwordsSpecify WITH
ADMIN
OPTION
to enable the grantee to:
Grant the privilege or role to another user or role, unless the role is a GLOBAL
role
Revoke the privilege or role from another user or role
Alter the privilege or role to change the authorization needed to access it
Drop the privilege or role
If you grant a system privilege or role to a user without specifying WITH
ADMIN
OPTION
, and then subsequently grant the privilege or role to the user WITH
ADMIN
OPTION
, then the user has the ADMIN
OPTION
on the privilege or role.
To revoke the ADMIN
OPTION
on a system privilege or role from a user, you must revoke the privilege or role from the user altogether and then grant the privilege or role to the user without the ADMIN
OPTION
.
TO
grantee_clause
identifies users or roles to which the system privilege, role, or object privilege is granted.
Restriction on Grantees A user, role, or PUBLIC
cannot appear more than once in TO
grantee_clause.
Specify PUBLIC
to grant the privileges to all users. Oracle recommends against granting system privileges to PUBLIC
.
Restrictions on Granting System Privileges and Roles Privileges and roles are subject to the following restrictions:
A privilege or role cannot appear more than once in the list of privileges and roles to be granted.
You cannot grant a role to itself.
You cannot grant a role IDENTIFIED
GLOBALLY
to anything.
You cannot grant a role IDENTIFIED
EXTERNALLY
to a global user or global role.
You cannot grant roles circularly. For example, if you grant the role banker
to the role teller
, then you cannot subsequently grant teller
to banker
.
Use these clauses to grant object privileges.
Specify the object privilege you want to grant. You can specify any of the values described Table 18-2. When you grant an object privilege on a editionable object, either to a user or to a role, the object is actualized in the edition in which the grant is made. Refer to CREATE EDITION for information on editionable object types and editions.
Note:
To grantSELECT
on a view to another user, either you must own all of the objects underlying the view or you must have been granted the SELECT
object privilege WITH
GRANT
OPTION
on all of those underlying objects. This is true even if the grantee already has SELECT
privileges on those underlying objects.Restriction on Object Privileges A privilege cannot appear more than once in the list of privileges to be granted.
Specify ALL
to grant all the privileges for the object that you have been granted with the GRANT
OPTION
. The user who owns the schema containing an object automatically has all privileges on the object with the GRANT
OPTION
. The keyword PRIVILEGES
is provided for semantic clarity and is optional.
Specify the table or view column on which privileges are to be granted. You can specify columns only when granting the INSERT
, REFERENCES
, or UPDATE
privilege. If you do not list columns, then the grantee has the specified privilege on all columns in the table or view.
For information on existing column object grants, query the USER_
, ALL_
, or DBA_COL_PRIVS
data dictionary view.
See Also:
Oracle Database Reference for information on the data dictionary views and "Granting Multiple Object Privileges on Individual Columns: Example"The on_object_clause
identifies the object on which the privileges are granted. Directory schema objects, editions, data mining models, and Java source and resource schema objects are identified separately because they reside in separate namespaces.
If you can make this grant only because you have the GRANT
ANY
OBJECT
PRIVILEGE
system privilege—that is, you are not the owner of object
, nor do you have object_privilege
on object
WITH
GRANT
OPTION
—then the effect of this grant is that you are acting on behalf of the object owner. The *_TAB_PRIVS
data dictionary views will reflect that this grant was made by the owner of object
.
See Also:
"Revoke Operations that Use GRANT ANY OBJECT PRIVILEGE: Example" for more information on using the GRANT
ANY
OBJECT
PRIVILEGE
system privilege for revoke operations
Specify WITH
GRANT
OPTION
to enable the grantee to grant the object privileges to other users and roles.
Restriction on Granting WITH GRANT OPTION You can specify WITH
GRANT
OPTION
only when granting to a user or to PUBLIC
, not when granting to a role.
Specify WITH
HIERARCHY
OPTION
to grant the specified object privilege on all subobjects of object
, such as subviews created under a view, including subobjects created subsequent to this statement.
This clause is meaningful only in combination with the SELECT
object privilege.
object Specify the schema object on which the privileges are to be granted. If you do not qualify object
with schema
, then the database assumes the object is in your own schema. The object can be one of the following types:
Table, view, or materialized view
Sequence
Procedure, function, or package
User-defined type
Synonym for any of the preceding items
Directory, library, operator, or indextype
Java source, class, or resource
You cannot grant privileges directly to a single partition of a partitioned table.
See Also:
"Granting Object Privileges on a Table to a User: Example", "Granting Object Privileges on a View: Example", and "Granting Object Privileges to a Sequence in Another Schema: Example"DIRECTORY directory_name Specify a directory schema object on which privileges are to be granted. You cannot qualify directory_name
with a schema name.
JAVA SOURCE | RESOURCE The JAVA
clause lets you specify a Java source or resource schema object on which privileges are to be granted.
See Also:
CREATE JAVAListings of System and Object Privileges
Note:
When you grant a privilege onANY
object, such as CREATE
ANY
CLUSTER
, the result is determined by the value of the O7_DICTIONARY_ACCESSIBILITY
initialization parameter. By default, this parameter is set to FALSE
, so that ANY
privileges give the grantee access to that type of object in all schemas except the SYS
schema. If you set O7_DICTIONARY_ACCESSIBILITY
to TRUE
, then the ANY
privileges also give the grantee access, in the SYS
schema, to all objects except Oracle Scheduler objects. For security reasons, Oracle recommends that you use this setting only with great caution.System Privilege Name | Operations Authorized |

Table 18-2 Object Privileges and the Operations They Authorize
Object Privilege | Operations Authorized |
---|---|
DIRECTORY PRIVILEGES |
The following directory privileges provide secured access to the files stored in the operating system directory to which the directory object serves as a pointer. The directory object contains the full path name of the operating system directory where the files reside. Because the files are actually stored outside the database, Oracle Database server processes also need to have appropriate file permissions on the file system server. Granting object privileges on the directory database object to individual database users, rather than on the operating system, allows the database to enforce security during file operations. |
Read files in the directory. |
|
Write files in the directory. This privilege is useful only in connection with external tables. It allows the grantee to determine whether the external table agent can write a log file or a bad file to the directory. Restriction: This privilege does not allow the grantee to write to a |
|
Execute a preprocessor program that resides in the directory. A preprocessor program converts data to a supported format when loading data records from an external table with the |

The following indextype privilege authorizes operations on indextypes. |
|
Reference an indextype. |
The following flashback data archive privilege authorizes operations on flashback data archives. |
|
|
Enable or disable historical tracking for a table. |
LIBRARY PRIVILEGE |
The following library privilege authorizes operations on a library. |

|
OBJECT TYPE PRIVILEGES |
The following object type privileges authorize operations on a database object type. |
Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object type. Place a breakpoint or stop at a line or instruction boundary within the type body. |
|
Use and reference the specified object and invoke its methods. Access, through a debugger, public variables, types, and methods defined on the object type. |
|
Create a subtype under this type. You can grant this object privilege only if you have the |
|
OLAP PRIVILEGES |
The following object privileges are valid if you are using Oracle Database with the OLAP option. |
Insert members into the OLAP cube dimension or measures into the measures folder. |
|
Change the definition of the OLAP cube dimension or cube. |
|
Delete members from the OLAP cube dimension or measures from the measures folder. |
|
View or query the OLAP cube or cube dimension. |
|
Update measure values of the OLAP cube or attribute values of the cube dimension. |
|
OPERATOR PRIVILEGE |
The following operator privilege authorizes operations on user-defined operators. |
Reference an operator. |
|
PROCEDURE, FUNCTION, PACKAGE PRIVILEGES |
The following procedure, function, and package privileges authorize operations on procedures, functions, and packages. These privileges also apply to Java sources, classes, and resources, which Oracle Database treats as though they were procedures for purposes of granting object privileges. |
Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object. Place a breakpoint or stop at a line or instruction boundary within the procedure, function, or package. This privilege grants access to the declarations in the method or package specification and body. |
|
|
Execute the procedure or function directly, or access any program object declared in the specification of a package, or compile the object implicitly during a call to a currently invalid or uncompiled function or procedure. This privilege does not allow the grantee to explicitly compile using Access, through a debugger, public variables, types, and methods defined on the procedure, function, or package. This privilege grants access to the declarations in the method or package specification only. Job scheduler objects are created using the Note: Users do not need this privilege to execute a procedure, function, or package indirectly. |
SCHEDULER PRIVILEGES |
Job scheduler objects are created using the |
|
Operations on job classes, programs, chains, and credentials. |
|
Modifications to jobs, programs, chains, credentials, and schedules. |
SEQUENCE PRIVILEGES |
The following sequence privileges authorize operations on a sequence. |
Change the sequence definition with the |
|
Examine and increment values of the sequence with the |
|
SYNONYM PRIVILEGES |
Synonym privileges are the same as the privileges for the target object. Granting a privilege on a synonym is equivalent to granting the privilege on the base object. Similarly, granting a privilege on a base object is equivalent to granting the privilege on all synonyms for the object. If you grant to a user a privilege on a synonym, then the user can use either the synonym name or the base object name in the SQL statement that exercises the privilege. |
TABLE PRIVILEGES |
The following table privileges authorize operations on a table. Any one of following object privileges allows the grantee to lock the table in any lock mode with the Note: For external tables, the only valid object privileges are |

Granting a System Privilege to a User: Example To grant the CREATE
SESSION
system privilege to the sample user hr
, allowing hr
to log on to Oracle Database, issue the following statement:
GRANT CREATE SESSION TO hr;
Granting System Privileges to a Role: Example The following statement grants appropriate system privileges to a data warehouse manager role, which was created in the "Creating a Role: Example":
GRANT CREATE ANY MATERIALIZED VIEW , ALTER ANY MATERIALIZED VIEW , DROP ANY MATERIALIZED VIEW , QUERY REWRITE , GLOBAL QUERY REWRITE TO dw_manager WITH ADMIN OPTION;
The dw_manager
privilege domain now contains the system privileges related to materialized views.
Granting a Role with the Admin Option: Example To grant the dw_manager
role with the ADMIN
OPTION
to the sample user sh
, issue the following statement:
GRANT dw_manager TO sh WITH ADMIN OPTION;
User sh
can now perform the following operations with the dw_manager
role:
Enable the role and exercise any privileges in the privilege domain of the role, including the CREATE
MATERIALIZED
VIEW
system privilege
Grant and revoke the role to and from other users
Drop the role
Granting Object Privileges to a Role: Example The following example grants the SELECT
object privileges to a data warehouse user role, which was created in the "Creating a Role: Example":
GRANT SELECT ON sh.sales TO warehouse_user;
Granting a Role to a Role: Example The following statement grants the warehouse_user
role to the dw_manager
role. Both roles were created in the "Creating a Role: Example":
GRANT warehouse_user TO dw_manager;
The dw_manager
role now contains all of the privileges in the domain of the warehouse_user
role.
Granting an Object Privilege on a Directory: Example To grant READ
on directory bfile_dir
to user hr
, with the GRANT
OPTION
, issue the following statement:
GRANT READ ON DIRECTORY bfile_dir TO hr WITH GRANT OPTION;
Granting Object Privileges on a Table to a User: Example To grant all privileges on the table oe.bonuses
, which was created in "Merging into a Table: Example", to the user hr
with the GRANT
OPTION
, issue the following statement:
GRANT ALL ON bonuses TO hr WITH GRANT OPTION;
The user hr
can subsequently perform the following operations:
Exercise any privilege on the bonuses
table
Grant any privilege on the bonuses
table to another user or role
Granting Object Privileges on a View: Example To grant SELECT
and UPDATE
privileges on the view emp_view
, which was created in "Creating a View: Example", to all users, issue the following statement:
GRANT SELECT, UPDATE ON emp_view TO PUBLIC;
All users can subsequently query and update the view of employee details.
Granting Object Privileges to a Sequence in Another Schema: Example To grant SELECT
privilege on the customers_seq
sequence in the schema oe
to the user hr
, issue the following statement:
GRANT SELECT ON oe.customers_seq TO hr;
The user hr
can subsequently generate the next value of the sequence with the following statement:
SELECT oe.customers_seq.NEXTVAL FROM DUAL;
Granting Multiple Object Privileges on Individual Columns: Example To grant to user oe
the REFERENCES
privilege on the employee_id
column and the UPDATE
privilege on the employee_id
, salary
, and commission_pct
columns of the employees
table in the schema hr
, issue the following statement:
GRANT REFERENCES (employee_id), UPDATE (employee_id, salary, commission_pct) ON hr.employees TO oe;
The user oe
can subsequently update values of the employee_id
, salary
, and commission_pct
columns. User oe
can also define referential integrity constraints that refer to the employee_id
column. However, because the GRANT
statement lists only these columns, oe
cannot perform operations on any of the other columns of the employees
table.
For example, oe
can create a table with a constraint:
CREATE TABLE dependent (dependno NUMBER, dependname VARCHAR2(10), employee NUMBER CONSTRAINT in_emp REFERENCES hr.employees(employee_id) );
The constraint in_emp
ensures that all dependents in the dependent
table correspond to an employee in the employees
table in the schema hr
.
