I have a column called createdate of datetime datatype. I want to extract data between today and yesterday.

select * from table1(nolock) where createdate ='2018-06-01' --not getting any output

I want something like this:

select * from table1(nolock) where createdate between '2018-06-01' and '2018-06-02'

Rather than hard coding the date, I need between dateadd(d,-1,getdate()) and getdate(), but getdate() gives current timestamp. How can I search for the whole day like 2018-06-02 rather than 2018-06-02 02:12:13.423?

  • As a side note, please don't use nolock hint unless there's a good reason for it - and you are well aware of its side effects. – vonPryz Sep 25 at 19:19

You can always find today (with no time) using SELECT CONVERT(date, GETDATE());.

So to find all of the data for yesterday, you say:

DECLARE @today date = GETDATE();

SELECT ...
WHERE createDate >= DATEADD(DAY, -1, @today)
  AND createDate <  @today;

For today, it's a simple change:

WHERE createDate >= @today
  AND createDate <  DATEADD(DAY, 1, @today);

Community wiki answer - please edit to improve:

Your condition dateadd(d,-1,getdate()) and getdate() is almost right.

You need for the yesterday value to get rid of time like:

dateadd(day,datediff(day,0,getdate())-1,0)

So your condition will look like this:

where createDate >= dateadd(day, datediff(day, 0, getdate()) - 1, 0)  
  and createDate  < getdate()

If you only want things from yesterday, it should be:

WHERE     (txtDateTime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (txtDateTime < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0))
