Question

示例：

Table A

From_Date     To_Date        
2016-02-22    2016-02-29


Output
-------

2016-02-23
2016-02-24
2016-02-25
2016-02-26
2016-02-27
2016-02-28

输出应该是这样的。

两列都在同一个表A中。

我想显示这两列之间的日期。

Answer 1

你的意思是：

select *
from table_name
where from_date >= '2016-02-22' and to_date <= '2016-05-16'

Answer 2

如果From_Date和To_Date是变量：

DECLARE @From_Date date = '2016-02-22',
        @To_Date date = '2016-05-16'

SELECT *
FROM YourTable
WHERE DateField between @From_Date and @To_Date

如果没有，那么：

SELECT *
FROM YourTable
WHERE DateField between '2016-02-22' and '2016-05-16'

在另一张表中：

SELECT y.*
FROM YourTable y
INNER JOIN TableWithDate d
    ON y.DateField between d.From_Date and d.To_Date

通过递归CTE获得您想要的输出（假设[Table A]中的字符串为'2016-02-22'，'2016-02-29'为From_Date，To_Date）：< / p>

;WITH recurs AS (
    SELECT DATEADD(day,1,From_Date) as date_, To_Date
    FROM [Table A]
    UNION ALL
    SELECT DATEADD(day,1,date_), To_Date
    FROM recurs r
    WHERE date_ < DATEADD(day,-1,To_Date)
)

SELECT date_
FROM recurs

输出：

date_
2016-02-23
2016-02-24
2016-02-25
2016-02-26
2016-02-27
2016-02-28
