Try this: SELECT CONVERT( varchar, GETDATE() , 101)

You can change the 101 to any other number of formats to fit your need...

Datetime value will always have part time. That's why it's named DATE-TIME.

The best you can do is to make time part = 00:00:00.000

Is it what you are after?

DECLARE @Value AS datetime

SET @Value = '11/20/2006'

SELECT @Value

SELECT CONVERT( varchar, @Value, 101)

Can you elaborate? Your two choices: smalldatetime and datetime will yield "time". Are you using this value in a select statement or passing it to another database or a front-end application?

Thanks.

I have data in one table without time & while writing the query i have the statment says col1> getdate(), which gives different result as getdate comes with time so i want only date part not time part.

Hop this will give you an overview of what i am doing.

If I am understanding you correctly, you have a column in one table that is varchar with a date only as the entry; I do not know any other datatype which would support a date with no time. SQL Server should be able to handle the conversion implicitly without having to use these functions to change your GETDATE().

Not knowing your indexing, etc., I cannot comment on the optimization plan effects.

If you can give us an example, (including a small set of data and the table designs) of what you are hoping to achieve: your desired results and you actual results. That may help me or someone else recognize the problem...

When SQL Server converts a date stored as a string without a time value to a datetime, it assumes the time to be 00:00:00.000 AM. So even if you do not see a time value, when it is compared as a date, it will be done so as being 12 AM.

If you wnt to find rows where Col1 is today's date or later, then either do what Farrell suggested (converting back to datetime) or use the DateDiff() function to check to see if the time difference is more than 24 hours different.

Where DateDiff(day, Col1, getdate) >= 1

Or

Where DateDiff(hour, Col1, getdate) >= 24

I'm not sure if this is what your after but I found this snip out there somewhere onetime and use it all over. Better performance that the convert.

Select

-- Standard date with time

getdate() As DateWithTime,

-- Returns Date Portion Only

dateadd(d, 0, datediff(d, 0, getdate())) As DateOnly

Good luck

Tom

I think that will still return a "datetime" value. Look it up in BOL. (It returned the 12:00:00 AM value in my Query Analyzer)

Thanks a lot for all your help.

I wanted my final output as datetime.

-- Returns Date Portion Only
dateadd(d, 0, datediff(d, 0, getdate())) As DateOnly

That SQL was just what I was looking for. Thanks Tom! 🙂

I was doing something a little different. I had a column of dates that needed to be put in the MM/DD/YYYY format so it could be imported into SAS.

Most of the examples used getdate(), but Farrell Keough's example worked perfectly for me!

I used SELECT CONVERT(varchar, Dte_Eligibility_Begins , 101) and it converted 2008-01-01 00:00:00 to 01/01/2008.

Some of the other examples still put the time part in, even on just using getdate().

Thanks for the help.

Looks like confusing running around this thread.

I think what the OP mean't by no time was '00:00.00' which is actually still time, it's just the beginning of the date.
