Set Operators in View Definitions - Teradata Vantage

Set operators are permitted within view definitions.

For example, the following REPLACE VIEW statement uses UNION within a view definition:

REPLACE VIEW view_1 AS 
   SELECT x1,y1 
   FROM table_1 
   UNION 
   SELECT x2,y2 
   FROM table_2;

GROUP BY can be used within views with set operators.
