Ms SQL Date Only Without Time

MS SQL Date Only Without Time

that is very bad for performance, take a look at Only In A Database Can You Get 1000% + Improvement By Changing A Few Lines Of Code

functions on the left side of the operator are bad

here is what you need to do

declare @d datetime
select @d =  '2008-12-1 14:30:12'

where tstamp >= dateadd(dd, datediff(dd, 0, @d)+0, 0)
and tstamp < dateadd(dd, datediff(dd, 0, @d)+1, 0)

Run this to see what it does

select dateadd(dd, datediff(dd, 0, getdate())+1, 0)
select dateadd(dd, datediff(dd, 0, getdate())+0, 0)

How to select date without time in SQL

I guess he wants a string.

select convert(varchar(10), '2011-02-25 21:17:33.933', 120)

120 here tells the convert function that we pass the input date in the following format: yyyy-mm-dd hh:mi:ss.

DATETIME gives date without time in SQL Server

Exactly as I suspected:

[START_TIME] [date] NOT NULL,
[END_TIME] [date] NOT NULL,

If you provide a datetime value to a date datatype the time part of the value will be lost. Try:

DECLARE @d date;
SET @d = '2018-08-02T11:15:59.462'
SELECT @d;

Note it returns 2018-08-02. A date is just that, a date. A datetime, datetime2 or datetimeoffset needs to be used to store a date and time. You'll need to fix your table to resolve this:

ALTER TABLE dbo.SETTLEMENT_WIN ALTER COLUMN [START_TIME] datetime2(0) NOT NULL;
ALTER TABLE dbo.SETTLEMENT_WIN ALTER COLUMN [END_TIME] datetime2(0) NOT NULL;

Then you can insert a date and time value in your table.

How to return only the Date from a SQL Server DateTime datatype

SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, @your_date))

for example

SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))

gives me

2008-09-22 00:00:00.000

Pros:

• No varchar<->datetime conversions required
• No need to think about locale

how to query where date with time = date without time in ms sql

Try like this

SELECT * FROM  Bookings WHERE Convert(VARCHAR(10),StartTime,101) =  Convert(Varchar(10),'2/15/2014',101)

If you are using SQL SERVER 2012

Try this

 SELECT * FROM  Bookings WHERE FORMAT(StartTime,'M/dd/yyyy') = FORMAT('2/15/2014','M/dd/yyyy')

Best way to compare dates without time in SQL Server

Don't use convert - that involves strings for no reason. A trick is that a datetime is actually a numeric, and the days is the integer part (time is the decimal fraction); hence the day is the FLOOR of the value: this is then just math, not strings - much faster

declare @when datetime = GETUTCDATE()
select @when -- date + time
declare @day datetime = CAST(FLOOR(CAST(@when as float)) as datetime)
select @day -- date only

In your case, no need to convert back to datetime; and using a range allows the most efficent comparisons (especially if indexed):

declare @when datetime = 'Feb 15 2012  7:00:00:000PM'
declare @min datetime = FLOOR(CAST(@when as float))
declare @max datetime = DATEADD(day, 1, @min)

select * from sampleTable where DateCreated >= @min and DateCreated < @max

Best approach to remove time part of datetime in SQL Server

Strictly, method a is the least resource intensive:

a) select DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

Proven less CPU intensive for the same total duration a million rows by someone with way too much time on their hands: Most efficient way in SQL Server to get a date from date+time?

I saw a similar test elsewhere with similar results too.

I prefer the DATEADD/DATEDIFF because:

• varchar is subject to language/dateformat issues
  
  Example: Why is my CASE expression non-deterministic?
• float relies on internal storage
• it extends to work out first day of month, tomorrow, etc by changing "0" base

Edit, Oct 2011

For SQL Server 2008+, you can CAST to date i.e. CAST(getdate() AS date). Or just use date datatype so no time to remove.

Edit, Jan 2012

A worked example of how flexible this is: Need to calculate by rounded time or date figure in sql server

Edit, May 2012

Do not use this in WHERE clauses and the like without thinking: adding a function or CAST to a column invalidates index usage. See number 2 here Common SQL Programming Mistakes

Now, this does have an example of later SQL Server optimiser versions managing CAST to date correctly, but generally it will be a bad idea ...

Edit, Sep 2018, for datetime2

DECLARE @datetime2value datetime2 = '02180912 11:45' --this is deliberately within datetime2, year 0218
DECLARE @datetime2epoch datetime2 = '19000101'

select DATEADD(dd, DATEDIFF(dd, @datetime2epoch, @datetime2value), @datetime2epoch)
