Answer 1

select id, userName
from YourTable
where CAST(date AS DATE) = CAST(GETDATE() AS DATE)

Function GETDATE() returns the current date and time.

CAST(column as TYPE) will threat DateTime as just Date to omit differences in Time

Answer 2

获取今天的日期记录：

select * from tablename where date column between '2011-10-25 00:00:00' And '2011-10-25 23:59:59'

Answer 3

select * from yourtable where date = CONVERT(VARCHAR(20),GETDATE(),101) //希望这对获取当前日期值有所帮助..

Answer 4

This query compares only the date piece of today, ignoring the time. It works in MS SQL Server, I'm not sure about other implimentations:

select *
from YourTable
where convert(datetime, floor(convert(float, GETDATE()))) = [date]

Answer 5

select *
from YourTable
where
  [date] >= '20110311' and
  [date] < '20110312'

If you want it for today (always) you can use this

select *
from YourTable
where
  [date] >= dateadd(d, datediff(d, 0, getdate()), 0) and
  [date] < dateadd(d, datediff(d, 0, getdate())+1, 0)

Last 10 days.

select *
from YourTable
where
  [date] >= dateadd(d, datediff(d, 0, getdate())-9, 0)

Edit 1 Query with sample data and result

Table definition

create table users
  (name varchar(20),
   user_register_date datetime)

Data

insert into users values ('user today', getdate())
insert into users values ('user yesterday', getdate()-1)
insert into users values ('user 9 days ago', getdate()-9)
insert into users values ('user 10 days ago', getdate()-10)

Query

select *
from users
where user_register_date >= dateadd(d, datediff(d, 0, getdate())-9, 0)

Result

name                 user_register_date
-------------------- -----------------------
user today           2011-04-14 08:29:28.407
user yesterday       2011-04-13 08:29:28.410
user 9 days ago      2011-04-05 08:29:28.410

Answer 6

SELECT * from YourTable
WHERE cast(convert(varchar(10),yourdate,101) as datetime) = 
cast(convert(varchar(10),[any day you want],101) as datetime)

Hope this helps. Just replace [any day you want] with a date or datetime value

The CAST function is equivalent to the CONVERT function, except convert allows for some formatting options. In my example, I simply trimmed off the time from the date.
