Description

ALL or ALL PRIVILEGES

Grants one or more privileges. The privileges granted are all those grantable privileges that the authorization ID of the statement has on the specified sequences. Note that granting ALL PRIVILEGES on a sequence is not the same as granting the system authority of *ALL.

If you do not use ALL, you must use one or more of the keywords listed below. Each keyword grants the privilege described.

ALTER

Grants the privilege to use the ALTER SEQUENCE, COMMENT, and LABEL statements on a sequence.

USAGE

Grants the privilege to use the sequence in NEXT VALUE or PREVIOUS VALUE expressions.

ON SEQUENCE sequence-name

Identifies the sequences on which the privilege is granted. The sequence-name must identify a sequence that exists at the current server.

TO

Indicates to whom the privileges are granted.

authorization-name,...

Lists one or more authorization IDs.

PUBLIC

Grants the privileges to a set of users (authorization IDs). For more information, see Authorization, privileges and object ownership.

WITH GRANT OPTION

Allows the specified authorization-names to grant privileges on the sequences specified in the ON clause to other users.

If WITH GRANT OPTION is omitted, the specified authorization-names cannot grant the USAGE privilege to others unless they have received that authority from some other source (for example, from a grant of the system authority *OBJMGT).

Note

Corresponding System Authorities: GRANT and REVOKE statements assign and remove system authorities for SQL objects. The following table describes the system authorities that correspond to the SQL privileges:

Corresponding System Authorities When Checking Privileges to a Sequence: The following table describes the system authorities that correspond to the SQL privileges when checking privileges to a sequence. The left column lists the SQL privilege. The right column lists the equivalent system authorities.

Example

Grant any user the USAGE privilege on a sequence called ORG_SEQ.
