如何在sql server中获取当前/今天的日期数据

Question

如何编写查询以获取SQL server中的今天日期数据？

select * from tbl_name where date = <Todays_date>

Answer 1

正确答案取决于datecolumn的确切类型。假设它是Date：

类型

select * from tbl_name 
where datecolumn = cast(getdate() as Date)

如果是DateTime：

select * from tbl_name 
where cast(datecolumn as Date) = cast(getdate() as Date)

Answer 2

select * from tbl_name where date = cast(getdate() as Date)

代表CAST查看http://msdn.microsoft.com/en-us/library/ms187928.aspx和GETDATE()查看https://msdn.microsoft.com/en-IN/library/ms188383.aspx

Answer 3

似乎Mitch Wheat的答案不是sargable，虽然我不确定这是真的。

请注意：LHS上的DATEDIFF()（或其他计算）不可分，而Cast(x to Date)则为{。}}。

SELECT * 
FROM tbl_name 
WHERE date >= cast(getdate() as date)
and date < cast(getdate()+1 as date)

Answer 4

select * from tbl_name where date(column_name) = CURDATE();

现在您可以获取今天插入的行
