GRANT (Distinct Type Privileges)

This form of the GRANT statement grants privileges on a distinct type.

Invocation

This statement can be embedded in an application program or issued interactively. It is an executable statement that can be dynamically prepared.

Authorization

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

For each distinct type identified in the statement:
- Every privilege specified in the statement
- The system authority of *OBJMGT on the distinct type
- The system authority *EXECUTE on the library containing the distinct type
Administrative authority

If WITH GRANT OPTION is specified, the privileges held by the authorization ID of the statement must include at least one of the following:

Ownership of the distinct type
Administrative authority

         '-PUBLIC-------------'    '-WITH GRANT OPTION-'

Grants one or more privileges. The privileges granted are all those grantable privileges that the authorization ID of the statement has on the specified distinct types. Note that granting ALL PRIVILEGES on a distinct type 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 COMMENT statement.

USAGE

Grants the privilege to use the distinct type in tables, functions, or procedures.

ON DISTINCT TYPE distinct-type-name

Identifies the distinct types on which the privilege is granted. The distinct-type-name must identify a distinct type 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 distinct types 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:

Table 60. Privileges Granted to or Revoked from Distinct Types
SQL Privilege	Corresponding System Authorities when Granting to or Revoking from a Distinct Type
ALL (Grant or revoke of ALL grants or revokes only those privileges the authorization ID of the statement has)	OBJALTER OBJOPR EXECUTE OBJMGT (Revoke only)
ALTER	*OBJALTER
USAGE	EXECUTE OBJOPR
WITH GRANT OPTION	*OBJMGT

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

Table 61. Corresponding System Authorities When Checking Privileges to a Distinct Type
SQL Privilege	Corresponding System Authorities when Granting to or Revoking from a Distinct Type
ALTER	*OBJALTER
USAGE	EXECUTE and OBJOPR

When USAGE privilege is required: USAGE privilege is required when a distinct type is explicitly referenced in an SQL statement. For example, in a statement that contains a CAST specification or in a CREATE TABLE statement. The USAGE privilege is not required when a distinct type is indirectly referenced. For example, when a view references a column of a table that has a distinct data type.

Syntax alternatives: The following keywords are synonyms supported for compatibility to prior releases. These keywords are non-standard and should not be used:

The keyword DATA can be used as a synonym for DISTINCT.

Example

Grant the USAGE privilege on distinct type SHOE_SIZE to user JONES. This GRANT statement does not give JONES the privilege to execute the cast functions that are associated with the distinct type SHOE_SIZE.

GRANT USAGE
  ON DISTINCT TYPE SHOE_SIZE
  TO JONES
