REVOKE {ALTER | USAGE} [,...] ON SEQUENCE sequence-name [,...] FROM {authorization-name | PUBLIC} [,...] [BY {authorization-name | ALL} [,...]] [RESTRICT]
Revokes the USAGE privilege to use a sequence. This privilege is needed when the NEXT VALUE or PREVIOUS VALUE expression is invoked for a sequence name.
Identifies the sequence. The name, including the implicit or explicit schema qualifier, must uniquely identify an existing sequence at the current server. If no sequence by this name exists in the explicitly or implicitly specified schema, an error occurs. sequence-name must not be the name of an internal sequence object that is generated by the system for an identity column.
Lists one or more authorization IDs. Do not use the same authorization ID more than once. The value of CURRENT RULES determines if you can use the ID of the REVOKE statement itself (to revoke privileges from yourself). When CURRENT RULES is:
Lists grantors who have granted privileges and revokes each named privilege that was explicitly granted to some named user by one of the named grantors. Only an authorization ID with SYSADM or SYSCTRL authority can use BY, even if the authorization ID names only itself in the BY clause.
Lists one or more authorization IDs of users who were the grantors of the privileges named. Do not use the same authorization ID more than once. Each grantor listed must have explicitly granted some named privilege to all named users.
Revokes each named privilege from all named users who were explicitly granted the privilege, regardless of who granted it.
