CREATE TABLE a(b VARCHAR0);
INSERT INTO a VALUES(0);
CREATE TABLE c(d e);
CREATE VIEW f(g, h) AS SELECT b, 0 FROM a UNION SELECT d, 0 FROM c;
SELECT(SELECT lead(g = g) OVER() FROM f GROUP BY h);

Simplified test case

  CREATE TABLE a(b TEXT);  INSERT INTO a VALUES(0),(4),(9);
  CREATE TABLE c(d NUM);
  CREATE VIEW f(g, h) AS SELECT b, 0 FROM a UNION SELECT d, d FROM c;
  SELECT g = g FROM f GROUP BY h;
