You can use the MODIFY USER statement to change or drop CONSTRAINT object assignments for an existing user.
The following example changes assignments made in Assigning Security Constraints in a CREATE USER Statement:
MODIFY USER Joe_Smith AS CONSTRAINT = Classification_Level (TopSecret, Unclassified DEFAULT), CONSTRAINT = Classification_Country (NULL) CONSTRAINT = Classification_Job (Analyst) ;
where:
Syntax Element | Description |
---|---|
Classification_Level(TopSecret, Unclassified DEFAULT) | Raises the user classification level by replacing Secret with TopSecret, while retaining the DEFAULT Unclassified level. |
Classification_Country(NULL) | Drops the Classification_Country constraint assignment from the user. |
Classification_Job (Analyst) | Adds the new hierarchical category Classification_Job, and assigns the Analyst classification level. |
A new or changed security constraint assignment takes effect at the next user logon.
