sql - how to get current/Todays date data in sql server

Question

how to write query to get today's date data in SQL server ?

select * from tbl_name where date = <Todays_date>

Answer 1

The correct answer will depend of the exact type of your datecolumn. Assuming it is of type Date :

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

If it is DateTime:

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

Answer 2

似乎 Mitch Wheat 的回答不是sargable，虽然我不确定这是真的。

请注意：DATEDIFF()LHS 上的 a（或其他计算）不是 Sargable，而 as Cast(x to Date)is。

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

Answer 3

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

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

Answer 4

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