 The name of the relation for which you want to delete an ACL entry.

 The name of the view for which you want to delete an ACL entry.

 The name of the local field in a specified relation for which you
 want to delete an ACL entry.

 Rights on a field are determined by the rights defined on the
 relation combined with those specified for the specific relation ACL.

 A number that identifies the entry within the specified access
 control list whose protection you want to delete.

 A VMS user identifier that designates the entry within the specified
 access control list whose protection you want to delete.

 Example 1

 Delete an ACL entry identified by a sequence number:

 RDO> DELETE PROTECTION FOR DATABASE 3.

 This statement deletes an entry identified by sequence number.  All
 the entries following the deleted entry are given the next lower
 sequence number.


 Example 2

 Delete an ACL entry identified by a UIC:

 RDO> DELETE PROTECTION FOR RELATION JOB_HISTORY [CLERKS,SMITH].

 This statement deletes the entry identified by [CLERKS,SMITH].

 You must have the Rdb/VMS CONTROL privilege to use the DELETE
 PROTECTION statement.

 Revoking a privilege takes effect after the users detaches and
 attaches to the database again.

 You must execute this statement in a read/write transaction.  If
 there is no active transaction and you issue this statement, Rdb/VMS
 starts a read/write transaction implicitly.

 Other users are allowed to be attached to the database when you issue
 the DELETE PROTECTION statement.
