-- Basic CROSS JOIN
SELECT * FROM small_table CROSS JOIN another_table ORDER BY a, b;

-- CROSS JOIN with WHERE filter
SELECT * FROM small_table CROSS JOIN another_table WHERE a + b < 25 ORDER BY a, b;

-- CROSS JOIN with aliases
SELECT s.a, t.b FROM small_table s CROSS JOIN another_table t WHERE s.a = 1 ORDER BY b;
