不使用表格选择两个日期之间的所有日期(生成日期列表)
问题描述：
有没有一种方法可以获取两个日期之间的所有日期而无需使用任何MySQL表
Is there a way to get all dates between two dates without using any MySQL table
类似:
SELECT date BETWEEN '2012-02-10' AND '2012-02-15'
这将导致以下结果:
out put date list
2012-02-10
...
2012-02-15
答
以下是查询:
该查询在两个数据库中均给出正确的结果:MariaDB& MySQL.
Here is the query:
This query gives proper result in both the databases : MariaDB & MySQL.
SELECT ADDDATE('2012-02-10', INTERVAL @i:=@i+1 DAY) AS DAY
FROM (
SELECT a.a
FROM (SELECT 0 AS a 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) AS a
CROSS JOIN (SELECT 0 AS a 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) AS b
CROSS JOIN (SELECT 0 AS a 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) AS c
) a
JOIN (SELECT @i := -1) r1
WHERE
@i < DATEDIFF('2012-02-15', '2012-02-10')
