[sql] How to select rows for a specific date, ignoring time in SQL Server

Given a table with a datetime column, how do I query for rows where the date matches the value I specify but ignores the time portion?

For example, select * from sales where salesDate = '11/11/2010'

For this query we don't care about the time. Other queries require the time component so we can't store only the date component.

Thanks!

I know it's been a while on this question, but I was just looking for the same answer and found this seems to be the simplest solution:

select * from sales where datediff(dd, salesDate, '20101111') = 0

I actually use it more to find things within the last day or two, so my version looks like this:

select * from sales where datediff(dd, salesDate, getdate()) = 0

And by changing the 0 for today to a 1 I get yesterday's transactions, 2 is the day before that, and so on. And if you want everything for the last week, just change the equals to a less-than-or-equal-to:

select * from sales where datediff(dd, salesDate, getdate()) <= 7

select 
  * 
from sales 
where 
  dateadd(dd, datediff(dd, 0, salesDate), 0) = '11/11/2010'

select * from sales where salesDate between '11/11/2010' and '12/11/2010' --if using dd/mm/yyyy

The more correct way to do it:

DECLARE @myDate datetime
SET @myDate = '11/11/2010'
select * from sales where salesDate>=@myDate and salesDate<dateadd(dd,1,@myDate)

If only the date is specified, it means total midnight. If you want to make sure intervals don't overlap, switch the between with a pair of >= and <

you can do it within one single statement, but it's just that the value is used twice.

I know this is an old topic, but I managed to do it in this simple way:

select count(*) from `tablename`
where date(`datecolumn`) = '2021-02-17';

Something like this:

select 
  * 
from sales 
where salesDate >= '11/11/2010' 
  AND salesDate < (Convert(datetime, '11/11/2010') + 1)

Try this:

true
select cast(salesDate as date) [date] from sales where salesDate = '2010/11/11'
false
select cast(salesDate as date) [date] from sales where salesDate = '11/11/2010'
