SQL Select 'n' records without a Table

Question

Is there a way of selecting a specific number of rows without creating a table. e.g. if i use the following:

SELECT 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

This is a good way if you need a long list (so you don't need lots of UNIONstatements:

WITH CTE_Numbers AS (
    SELECT n = 1
    UNION ALL
    SELECT n + 1 FROM CTE_Numbers WHERE n < 10 
)
SELECT n FROM CTE_Numbers
