MySQL 보기를 사용하여 날짜 범위에서 일수를 생성하는 방법은 무엇입니까?

이를 설명하기 위해 다음 뷰를 만듭니다. -

mysql> CREATE VIEW digits AS
    -> SELECT 0 AS digit UNION ALL
    -> SELECT 1 UNION ALL
    -> SELECT 2 UNION ALL
    -> SELECT 3 UNION ALL
    -> SELECT 4 UNION ALL
    -> SELECT 5 UNION ALL
    -> SELECT 6 UNION ALL
    -> SELECT 7 UNION ALL
    -> SELECT 8 UNION ALL
    -> SELECT 9;
Query OK, 0 rows affected (0.08 sec)

mysql> CREATE VIEW numbers AS SELECT ones.digit + tens.digit * 10 + hundreds.digit * 100 + thousands.digit * 1000 AS number FROM digits as ones, digits as tens, digits as hundreds, digits as thousands;
Query OK, 0 rows affected (0.09 sec)

mysql> CREATE VIEW dates1 AS SELECT SUBDATE(CURRENT_DATE(), number) AS date FROM numbers UNION ALL SELECT ADDDATE(CURRENT_DATE(), number + 1) AS date FROM numbers;
Query OK, 0 rows affected (0.09 sec)

mysql> Select date from dates1 where date between '2017-11-15' and '2017-11-30'order by date;
