sql - SQL Server 查询以显示预定到期日期之前 8 天和之后 8 天的行

Question

如我的标题中所述，是否可以显示符合条件的表格行：

SELECT * FROM TABLE 1
WHERE DueDate is less than 8 days and greater than 8 days to current date

提前致谢。

Answer 1

看一下BETWEEN表达式。

SELECT * 
FROM [Table]
WHERE DueDate BETWEEN GetDate() - 8 AND GetDate() + 8

此外，如果您需要消除时间组件，您可以执行以下操作：

DECLARE @CurrentDate DATETIME
SELECT @CurrentDate = CAST(FLOOR(CAST( GETDATE() AS FLOAT )) AS DATETIME)

SELECT * 
FROM [Table]
WHERE DueDate BETWEEN @CurrentDate - 8 AND @CurrentDate + 8

Answer 2

试试这个：

SELECT *
FROM yourTable
WHERE DueDate BETWEEN DATEADD(dd, -8, GETDATE()) AND DATEADD(dd, 8, GETDATE())
