Example 4 - Teradata Vantage - Analytics Database

In the following example, the condition in the RESET WHEN clause contains SELECT as a nested subquery. This is not allowed and results in an error.

        (ORDER BY 1
         RESET WHEN 1 in (SELECT 1))
   FROM t1;

Result:

   $
   *** Failure 3706 Syntax error: SELECT clause not supported in
