GRANT

Purpose

Use the GRANT statement to grant:

  • System privileges to users and roles.

  • Roles to users and roles. Both privileges and roles are either local, global, or external. Table 18-1 lists the system privileges (organized by the database object operated upon). Table 18-2 lists Oracle Database predefined roles.

  • Object privileges for a particular object to users, roles, and PUBLIC. Table 18-3 summarizes the object privileges that you can grant on each type of object. Table 18-4 lists object privileges and the operations that they authorize.

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, please 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.

Prerequisites

To grant a system privilege, you must either have been granted the system privilege with the ADMIN OPTION or have been granted the GRANT ANY PRIVILEGE system privilege.

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.

Semantics

grant_system_privileges

Use these clauses to grant system privileges.

system_privilege

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.

  • 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 Database provides the ALL PRIVILEGES shortcut for granting all the system privileges listed in Table 18-1, except the SELECT ANY DICTIONARY privilege.

role

Specify the role you want to grant. You can grant an Oracle Database predefined role or a user-defined role. Table 18-2 lists the predefined roles.

  • 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.

  • 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:

    "Granting a Role to a Role: Example" and CREATE ROLE for information on creating a user-defined role

IDENTIFIED BY Clause

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 passwords

WITH ADMIN OPTION

Specify WITH ADMIN OPTION to enable the grantee to:

  • Grant the role to another user or role, unless the role is a GLOBAL role

  • Revoke the role from another user or role

  • Alter the role to change the authorization needed to access it

  • Drop the 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.

grantee_clause

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.

PUBLIC Specify PUBLIC to grant the privileges to all users.

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.

grant_object_privileges

Use these clauses to grant object privileges.

object_privilege

Specify the object privilege you want to grant. You can specify any of the values shown in Table 18-3. See also Table 18-4.

Restriction on Object Privileges A privilege cannot appear more than once in the list of privileges to be granted.

ALL [PRIVILEGES]

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.

column

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.

on_object_clause

The on_object_clause identifies the object on which the privileges are granted. Directory schema objects 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:

WITH GRANT OPTION

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.

WITH HIERARCHY OPTION

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.

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.

CREATE JAVA

Listings of System and Object Privileges

Note:

When you grant a privilege on ANY 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.

Note 1: Oracle Database treats a Java class, source, or resource as if it were a procedure for purposes of granting object privileges.

Note 2: Job scheduler objects are created using the DBMS_SCHEDULER package. After these objects are created, you can grant the EXECUTE object privilege on job scheduler classes and programs. You can grant ALTER privilege on job scheduler jobs, programs, and schedules.

Note 3: The DELETE, INSERT, and UPDATE privileges can be granted only to updatable materialized views.

Table 18-4 Object Privileges and the Operations They Authorize

Object Privilege Operations Authorized

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 LOCK TABLE statement.

Note: For external tables, the only valid object privileges are ALTER and SELECT.

ALTER

Change the table definition with the ALTER TABLE statement.

DELETE

Remove rows from the table with the DELETE statement.

Note: You must grant the SELECT privilege on the table along with the DELETE privilege if the table is on a remote database.

DEBUG

Access, through a debugger:

  • PL/SQL code in the body of any triggers defined on the table

  • Information on SQL statements that reference the table directly

INDEX

Create an index on the table with the CREATE INDEX statement.

INSERT

Add new rows to the table with the INSERT statement.

REFERENCES

Create a constraint that refers to the table. You cannot grant this privilege to a role.

SELECT

Query the table with the SELECT statement.

UPDATE

Change data in the table with the UPDATE statement.

Note: You must grant the SELECT privilege on the table along with the UPDATE privilege if the table is on a remote database.

VIEW PRIVILEGES

The following view privileges authorize operations on a view. Any one of the following object privileges allows the grantee to lock the view in any lock mode with the LOCK TABLE statement.

To grant a privilege on a view, you must have that privilege with the GRANT OPTION on all of the base tables of the view.

DEBUG

Access, through a debugger:

  • PL/SQL code in the body of any triggers defined on the view

  • Information on SQL statements that reference the view directly

DELETE

Remove rows from the view with the DELETE statement.

INSERT

Add new rows to the view with the INSERT statement.

REFERENCES

Define foreign key constraints on the view.

SELECT

Query the view with the SELECT statement.

UNDER

Create a subview under this view. You can grant this object privilege only if you have the UNDER ANY VIEW privilege WITH GRANT OPTION on the immediate superview of this view.

UPDATE

Change data in the view with the UPDATE statement.

SEQUENCE PRIVILEGES

The following sequence privileges authorize operations on a sequence.

ALTER

Change the sequence definition with the ALTER SEQUENCE statement.

SELECT

Examine and increment values of the sequence with the CURRVAL and NEXTVAL pseudocolumns.

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.

DEBUG

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

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 ALTER PROCEDURE or ALTER FUNCTION. For explicit compilation you need the appropriate ALTER system privilege.

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.

Note: Users do not need this privilege to execute a procedure, function, or package indirectly.

See Also: Oracle Database Concepts and Oracle Database Application Developer's Guide - Fundamentals

MATERIALIZED VIEW PRIVILEGES

The following materialized view privileges authorize operations on a materialized view.

ON COMMIT REFRESH

Create a refresh-on-commit materialized view on the specified table.

QUERY REWRITE

Create a materialized view for query rewrite using the specified table.

SELECT

Query the materialized view with the SELECT statement.

SYNONYM PRIVILEGES

Synonym privileges are the same as the privileges for the base 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.

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

Read files in the directory.

WRITE

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 BFILE.

LIBRARY PRIVILEGE

The following library privilege authorizes operations on a library.

EXECUTE

Use and reference the specified object and invoke its methods.

OBJECT TYPE PRIVILEGES

The following object type privileges authorize operations on a database object type.

DEBUG

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.

EXECUTE

Use and reference the specified object and invoke its methods.

Access, through a debugger, public variables, types, and methods defined on the object type.

UNDER

Create a subtype under this type. You can grant this object privilege only if you have the UNDER ANY TYPE privilege WITH GRANT OPTION on the immediate supertype of this type.

INDEXTYPE PRIVILEGE

The following indextype privilege authorizes operations on indextypes.

EXECUTE

Reference an indextype.

OPERATOR PRIVILEGE

The following operator privilege authorizes operations on user-defined operators.

EXECUTE

Reference an operator.


Examples

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.
