Syntax
The ALTER USER statement has the following format:
[EXEC SQL] ALTER USER user_name
[ADD PRIVILEGES (priv {, priv}) |DROP PRIVILEGES (priv {, priv})]
[WITH with_item {, with_item}]
with_item = NOPRIVILEGES| PRIVILEGES = ( priv {, priv} )
| NOGROUP | GROUP = default_group
| SECURITY_AUDIT= ( audit_opt {,audit_opt})
| NOEXPIRE_DATE | EXPIRE_DATE = 'expire_date'
| DEFAULT_PRIVILEGES = (priv {,priv})| ALL | NODEFAULT_PRIVILEGES
| NOPROFILE | PROFILE= profile_name
| NOPASSWORD | PASSWORD = 'user_password'
| PASSWORD = X'encrypted_role_password'
| EXTERNAL_PASSWORD
| OLDPASSWORD = 'oldpassword'
| DBMS_AUTHENTICATION = 'REQUIRED' | 'OPTIONAL'
user_name
Specifies the user name. The user must be an existing Ingres user.
priv
Specifies a subject privilege, as described in Create User Syntax.
default group
Specifies the default group to which the user belongs. Must be an existing group. For details about groups, see
Create Group (see
CREATE GROUP). To specify that the user is not assigned to a group, use the NOGROUP option.
Default: NOGROUP if the group clause is omitted.
audit_opt
Defines security audit options, as described in Create User Syntax.
expire_date
Specifies an optional expiration date associated with the user. Any valid date can be used. Once the expiration date is reached, the user is no longer able to log on.
Default: NOEXPIRE_DATE if the EXPIRE_DATE clause is omitted.
DEFAULT_PRIVILEGES
Defines the privileges initially active when connecting to Ingres. These must be a subset of those privileges granted to the user.
When specified in conjunction with ADD PRIVILEGE, the default privileges are added to the existing default privileges for the user; otherwise, the specified default privileges will replace the existing default privileges for the user.
NODEFAULT_PRIVILEGES
Specifies that the session is started with no privileges active. Allows default privileges to be removed.
profile_name
Allows a profile to be specified for a particular user.
Default: NOPROFILE if the profile clause is omitted.
user_password
Allows a user to change her own password. If the OLDPASSWORD clause is missing or invalid, the password is unchanged. In addition, users with the maintain_users privilege can change or remove any password.
EXTERNAL_PASSWORD
Allows a user's password to be authenticated externally to Ingres. The password is passed to an external authentication server for authentication.
oldpassword
Specifies the user's old password.
DBMS_AUTHENTICATION =
Indicates whether DBMS authentication is required or optional.
'REQUIRED'
Allows only connection requests that specify the user name and password defined at the DBMS Server level and to a dbms_authentication enabled DBMS Server to succeed; other connections fail. Users with the "security" privilege, including the installation owner, cannot be defined as DBMS_AUTHENTICATION='REQUIRED'.
'OPTIONAL'
Allows connection requests that specify a user name and password defined at the operating system level, an installation password, or a Kerberos principle to succeed. In particular, this allows a local connection to a dbms_authentication server to succeed through implicit OS login authentication, without requiring the DBMS password.
Default: 'OPTIONAL'
