UNIX_TIMESTAMP in SQL Server
(9 answers)
Closed 7 years ago.
I am working with a query in SQL Server:
select datetimevalue
from temp;
Here datetimevalue column's datatype is datetime2 and I need to convert this value into timestamp.
In MySQL if I simply write:
select UNIX_TIMESTAM(datetimevalue)
from temp;
then it returns timestamp.
Is there any way to convert datetime in timestamp explicitly in SQL Server 2014?
SQL Server doesn't have a timestamp type. It used to have one in old versions but that type IS NOT a date & time value. In current versions timestamp is a deprecated synonym for rowversion.

I am trying to calculate the date difference and keep getting a column name error. I am new to SQL and learning from books and YouTube. Any assistance would be appreciated. I commented out the code not working
declare #rpDT datetime
set #rpDT = getdate()
SELECT [OrgKey]
,[visID]
,[visPatID]
,[visInternal]
,[visName]
,[visAssignedNS]
,[visAssignedRoom]
,[visAssignedBed]
,[visAdmitDT]
,isnull([visDischargeDT],#rpDT)as disDT
,datediff(day,[visAdmitDT],disDT) as Pt_days
FROM [MH_Pharmacy_Hub].[MC].[dbo_Visits]
SQL Server and most of the RDBMS do not allow to reference column at the same level. The closest equivalent to achieve similar effect is CROSS APPLY:
declare #rpDT datetime = getdate();
SELECT [OrgKey]
,[visID]
,[visPatID]
,[visInternal]
,[visName]
,[visAssignedNS]
,[visAssignedRoom]
,[visAssignedBed]
,[visAdmitDT]
,s.disDT
,datediff(day,[visAdmitDT],s.disDT) as Pt_days
FROM [MH_Pharmacy_Hub].[MC].[dbo_Visits]
CROSS APPLY (SELECT COALESCE([visDischargeDT],#rpDT)) AS s(disDT);

How to cast the DateTime to Time
(3 answers)
Closed 4 years ago.
I have a column in a SQL Server database of datatype DATETIME.
Currently the value is in this format: 2054-12-31T00:00:00.0000000
I want to convert this column values into this format : 2054-12-31T00:00:00
This conversion of value should happen while I select the column in SELECT query statement at run time
DATETIME as stored in SQL Server doesn't have any "format" associated with it - it's stored as a binary, 8 byte value.
In order to convert that binary value into a human-readable format, you need to check out the different styles for CONVERTing a DATETIME column into a string representation: https://learn.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql?view=sql-server-2017
You're probably looking for style #126 - so you can use this in your SELECT query:
SELECT
CONVERT(VARCHAR(50), YourDateTimeColumn, 126)
and that should do it

Why is SQL Server losing a millisecond?
(6 answers)
Closed 5 years ago.
The following query:
select convert(datetime, '2016-06-20 7:22:52.728')
gives me:
2016-06-20 07:22:52.727
In SQL Server v12.0.4100.1.
Whatever value I put for milliseconds, the result always has 1 less millisecond.
Am I missing something or is this a bug?
It's not a bug. The resolution of datetime is such that the final digit can only be one of a few values... Rounded to increments of .000, .003, or .007 seconds.
This is documented: Microsoft documentation for datetime (Transact-SQL)
That is how datetime works in sql server. If you want that millisecond, switch to datetime2([3-7]).
datetime accuracy is to 0.00333 second.
datetime2 accuracy is to 100 nanoseconds.
Date and Time Data Types and Functions (Transact-SQL)
Similarly, if you want to get the server time with additional accuracy, you would use sysdatetime() which returns datetime2(7) instead of getdate() which returns datetime.

How can I convert a Sql Server 2008 DateTimeOffset to a DateTime
(6 answers)
Closed 7 years ago.
I just need to change the date format from datatimeoffset to datetime while pulling the data
I will quote to "RichardTheKiwi"
declare #createdon datetimeoffset
set #createdon = '2008-12-19 17:30:09.1234567 +11:00'
select CONVERT(datetime2, #createdon, 1)
--Output: 2008-12-19 06:30:09.12
select convert(datetimeoffset,CONVERT(datetime2, #createdon, 1))
--Output: 2008-12-19 06:30:09.1234567 +00:00
Converting using almost any style will cause the datetime2 value to be converted to UTC.
Also, conversion from datetime2 to datetimeoffset simply sets the offset at +00:00, per the below, so it is a quick way to convert from Datetimeoffset(offset!=0) to Datetimeoffset(+00:00)

To store only time from DateTime into SQL Server 2005. I am using vs.net 2010 and SQL Server 2005
Like this
MyCurrent DataType
id int
EnterDate DateTime
Date string
Time string
// I want to like this STORE [Future out put]
id .... EnterDate Date Time
1 .... 4/11/2011 10:25:00 4/11/2011 10:25:00
2 .... 4/11/2011 10:32:10 4/11/2011 10:32:10
3 .... 4/11/2011 10:41:37 4/11/2011 10:41:37
So how to store only time value and how define datatype in SQL Server?
You can get Only time like this
Select CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond
Refer Sql server DateTime for more
I guess that you want to have three columns, one with datetime stamp, one with date and one with time only. if thats the case then
SELECT DATEPART(dd/mm/yyyy,EnterDate) AS Date
from table
this will get you all the dates from date time stamp, you can accomodate this in your insert query
SELECT DATEPART(hh:mm:ss,EnterDate) AS Time
from table
