MySQL에서 테이블에 쉼표로 구분된 목록을 설정하는 방법은 무엇입니까?

mysql> select 10 Number UNION ALL select 20 Number UNION ALL select 30 Number UNION ALL select 40 Number UNION ALL select 50 Number;

+--------+ | Number | +--------+ | 10 | | 20 | | 30 | | 40 | | 50 | +--------+ 5 rows in set (0.00 sec)

mysql> SELECT 1 a UNION ALL SELECT 2 a UNION ALL SELECT 3 a;

+---+ | a | +---+ | 1 | | 2 | | 3 | +---+ 3 rows in set (0.00 sec)
