GRANT (Index Privileges)

This form of the GRANT statement grants the CONTROL privilege on indexes.

Invocation

This statement can be embedded in an application program or issued through the use of dynamic SQL statements. It is an executable statement that can be dynamically prepared. However, if the bind option DYNAMICRULES BIND applies, the statement cannot be dynamically prepared (SQLSTATE 42509).

Authorization

The privileges held by the authorization ID of the statement must include at least one of the following:

• DBADM authority
• SYSADM authority.

Syntax

>>-GRANT--CONTROL--ON INDEX--index-name------------------------->
 
         .-,------------------------------------.
         V                                      |
>----TO----+-+-------+---authorization-name--+--+--------------><
           | +-USER--+                       |
           | '-GROUP-'                       |
           '-PUBLIC--------------------------'
 

Description

CONTROL

Grants the privilege to drop the index. This is the CONTROL authority for indexes, which is automatically granted to creators of indexes.

ON INDEX index-name

Identifies the index for which the CONTROL privilege is to be granted.

TO

Specifies to whom the privileges are granted.

USER

Specifies that the authorization-name identifies a user.

GROUP

Specifies that the authorization-name identifies a group name.

authorization-name,...

Lists the authorization IDs of one or more users or groups.

The list of authorization IDs cannot include the authorization ID of the user issuing the statement. (It is not possible to grant authorities to an authorization-name that is the same as the authorization ID of the GRANT statement.)

PUBLIC

Grants the privileges to all users.

Rules

• If neither USER nor GROUP is specified, then

  If the authorization-name is defined in the operating system only as GROUP, then GROUP is assumed.

  If the authorization-name is defined in the operating system only as USER or if it is undefined, USER is assumed.

  If the authorization-name is defined in the operating system as both, or DCE authentication is used, an error (SQLSTATE 56092) is raised.

Example

   GRANT CONTROL ON INDEX DEPTIDX TO USER USER4
