Programming Reference

If you are using a Teradata SQL based application, you can issue the GRANT and REVOKE statements. For more information on these SQL statements, see SQL Data Control Language.

In rare cases, a change in privileges could temporarily block the request of an active MONITOR session because the system must look up the new privileges before accepting any more requests from the affected user. If the system query is blocked by a lock on a Teradata Database dictionary table or if there is some other type of system processing bottleneck, you cannot issue any MONITOR requests until you acquire the new set of privileges. However, MONITOR requests submitted from the system console are not blocked by a change in privileges, because no privileges are necessary to issue MONITOR requests on the system console.
