Besides simple queries, UNION can be used within the following operations:

  • Derived tables
    You cannot use the HASH BY or LOCAL ORDER BY clauses in derived tables with set operators.
  • Subqueries
  • INSERT ... SELECT statements
  • Non-recursive CREATE VIEW statements

UNION ALL is the only valid set operator in a WITH RECURSIVE clause or CREATE RECURSIVE VIEW statement that defines a recursive query.
